Bev, your blog won't let me comment, so hoping you see this post.
Bev is writing her blog posts about using knit fabrics. I know of a wonderful tool that anyone who sews with knits would find invaluable.
Christine Johnson of http://www.cjpatterns.com/ has devised and written a "Perfect Sizing Worksheet". It enables you to calculate how much ease your finished knit garment will have, using fabric with any amount of stretch. For example, you measure your T-shirt pattern (or pants, or skirt, or whatever) at key points--bust, waist, hip. Write them on the worksheet. Determine the percentage of stretch your fabric has, and write it on the worksheet. Then, using her method of calculating, (easy math), you will know how much ease your Tshirt has using fabric with 25% stretch, 50% stretch, 75% stretch, or none at all.
It's genius. And it's free! To get it, go to the link above. Click on "Tips and Techniques". Next, click on "Perfect Sizing Worksheet". The first 3 pages are devoted to her own pattern line, where she has written all the measurements of her patterns. Go to page 4, where you'll see the "Perfect Sizing Worksheet". You can print it out, and use it every time you make a knit garment.
No more guessing how your knit garment is going to fit!
