I second HappiLeigh's suggestions. Also, you might want to look up some tutorials on sewing with knits. Technically, they should be sewn with different kinds of stitches (so the seams remain flexible like the fabric). You will also save yourself a lot of headaches if you make sure you have a food ball-point needle on your machine (it will specify "knits" on the package). have fun!
