Hello, dear friends! I'm knocking things off my list today. I've wound yarn, made stitch markers, taken pictures, and gotten all of the second-batch Time of Flowers kit orders out. Whee!
The PDF-only option for Time of Flowers is also now available and you can purchase it here.

This pattern is a digital download, and will be made available via a link on the screen immediately upon completion of payment. A link will also be sent (automatically and immediately) to the email address you use to order the pattern. Please save all downloads like this directly to your hard-drive in case you need to reprint in the future. As always, if you have any trouble, please let me know!
I'm sorry it has taken me so long to write this little informational post for you. I've been meaning to do it for ages. I get a fair amount of questions about substituting fabrics for my cross stitch patterns, and I'm going to try to break down a few of the options, and make things like stitch counts and fabric counts more clear than they perhaps might be to you right now. I'm going to take a lot of the information in this post from a tutorial that I wrote several years ago that you can always find on aliciapaulson.com; if you haven't read that and you're still finding yourself confused by this, give that a look and then let me know how I can help clarify further.
But, generally:
Counted cross stitch is not worked onto fabric that has been pre-printed. Counted cross stitch uses special fabrics that are called evenweave fabrics. These fabrics are woven so that they have the same number of warp threads (or, the threads running lengthwise through the fabric) and the same number of weft threads (or, the threads running crosswise, from selvedge to selvedge). In counted cross stitch (and from here on out, I'll just call it cross stitch) you work each stitch over the grid of perfect squares made by the warp and weft threads of your fabric.
Cross stitch can be done on different kinds of evenweave fabric, including evenweave linen, some woven ginghams, Aida cloth (which has a very ponounced grid that helps you see the holes into which your stitches go), waste canvas (which is a removable grid you temporarily apply to a piece of non-evenweave fabric that helps you place your stitches), and various other types of fabrics made especially for cross stitching. The fiber content and type of weave of the fabric you choose to use is largely a matter of personal preference. I use linen fabric for my kits (and the samples I've made up for my patterns), but a lot of people ask me if they can substitute Aida cloth. And the answer is: Yes! You can! I'll explain further.
What really matters is the "count" of the fabric. Thread count refers to the number of warp and weft threads per inch in the woven fabric. Stitch count refers to the number of cross stitches per inch you will have in your finished design. Aida cloth, for instance, is labeled according to stitch count; 10-count Aida cloth gives you 10 stitches per inch. Evenweave linen, however, is labeled according to thread count; 28-[thread]-count evenweave linen will give you a stitch count of 14, since cross stitch on this kind of linen is worked over 2 warp threads horizontally, and 2 weft threads vertically.

Look very closely at the photo above and you can see the crossed stitches going over 2 threads in each direction.
To work designs in cross stitch you follow a chart. Each colored box (generally with a symbol in it) on the chart represents one set of crossed stitches. Each set of crossed stitches is relative to the other stitches in the design, so you're only ever "counting" a few stitches away from the last stitch you just made. Each color on the chart represents a specific color of six-strand embroidery floss. A color key helps you define each color of floss.
(If the chart is too small for you to see comfortably, just enlarge it on a color copier. A good full-spectrum lamp is a must in dim light. I use this particular Ott light and I love it. When I'm not using it I fold it up and drop it down behind my side table and I never have to look at it. I used to have a big, huge gooseneck Ott light and I much prefer this tiny one; for what I'm doing, it works just as well, and in a small house is a better fit.)
"Count" is very important when choosing fabrics for cross stitching because the number of stitches per inch can drastically change the look of a design. In general, fabric with a lower stitch count will produce a coarser looking design, where the crosses will be larger and more pronounced. Fabric with a higher stitch count will produce designs that are smaller and finer. For the purposes of this post, I'm going to show you some different samples done on two different kinds of fabrics (Aida and linen) with different counts. So let's look at the first one:

This one, as indicated, is stitched on 8-count Aida fabric. Aida fabric is a good choice if you are a beginner to counted cross-stitch, or if you've struggled with evenweave fabrics in the past. If you look closely, you can see that the stitches are made directly into four little holes in each of the corners of a "square" space. Each square space equals one square on your chart. The holes are very pronounced and much easier to see than they are on linen.
Linen normally doesn't come in a stitch count this big (or, in other words, in a number this small — remember, stitch count number refers to stitches per inch; the lower the number, the fewer stitches per inch. The fewer stitches the stitches per inch, the bigger those stitches have to be). Eight stitches per inch is really quite big, but I wanted to use it to show you exactly how the same design translates into different sizes using different count fabrics. Here's the same design on 14-count Aida fabric:

Notice that the size of the scissors is fairly consistent here, but that the teacup is significantly smaller. Same design + different stitch count = different size finished piece. To see the same design on 28-thread-count linen (which, if you remember, is done over 2 threads, and so is actually 14 stitches per inch), regard this one:

See how those last two, even though they are on different kinds of fabric, are the same size? That's because they both have the same stitch count at 14 stitches per inch.
My seasonal series (both First Snow and Time of Flowers, and the upcoming designs for summer and fall) are all done on 32-count Belfast linen, which has a stitch count of 16 stitches per inches. Compare this to previous samples:

A bit smaller than the 14-counts.
A word about embroidery floss: All of the designs that I write patterns for that are worked on 28- or 32-count fabrics use 2 plies of floss per stitch. To separate plies, you simply take your length of floss by the middle and gently work the 2 plies away from the original 6. Some people even separate the 2 plies away from each other to sort of plump up the thread, but I don't. I don't like the way it looks. That's just personal preference, so do whatever works for you.
Now, here's something important to remember: Let's say that you want to stitch Time of Flowers but you don't want to do it on the fabric that I've used. That is perfectly fine, but let's look at something real quick. Please notice this line on the front cover of the pattern (and all patterns should have a line that reads very much like this on them):
Finished size of design area: 6"w x 8.5"h (15cm x 22cm); 101 stitches wide x 136 high on 32-count fabric
This means that, when finished, the width of the stitched area will be 6 inches, the height of the stitched area will be 8.5 inches on 32-count fabric. If you decide to use a different count fabric, you will need to recalculate the finished size of the design area. To do that, work backwards. Take the number of stitches the design is wide (101) and divide it by the stitch count of your fabric — let's just say you're going to use 8-count Aida.
101 stitches divided by 8 stitches per inch = 12.625 inches wide
AND
136 stitches (width) divided by 8 stitches per inch = 17 stitches high
Seeeeee how much bigger that difference translates to, in terms of the overall design? You're going from a 6" x 8.5" design that will fit into an 8" x 10" frame to an almost 13" x 17" design, not including ANY margins around the design area. That's a pretty big difference, so you just need to pay attention to that count. You can do any design on any fabric you'd like, but do make sure that you know how big the finished design area will be.
When you're purchasing fabric, you always want to make sure that you've got about 3" of extra fabric around each side of the design area. This allows you to easily mount your fabric in the hoop while you're working and also gives you enough space around your design area to stretch the fabric when you frame.
There are lots of places to purchase cross stitch supplies on-line. I know that Aida actually makes a 16-count fabric in Sea Lily (the color of linen I used for Time of Flowers) that can be purchased here. If you're local, I highly recommend you go out to Acorns and Threads sometime and visit Jeannine and the ladies there. This is such a gorgeous store with some of the best customer service you will receive anywhere, for anything. This store is a true local treasure, and it will inspire you more than I can say.
