Step 4: Tips & Tricks
After you have about two feet sewn, you can completely ditch the pins if you would like. As long as the yarns where you are sewing are straight, it will turn out just fine. During the cross-width sewing, you can make sure that the yarns look just how you want them before you sew the next line.
If you have to break your sewing for any reason (either running out of thread, or if the yarn catches or gets caught in the sewing gears) that is no problem at all, just make sure you tie the two thread ends together.
