Thank you all for the info and encouragement.
It works! http://I.imgur.com/kvDP66R.jpg This is the found loom from a few months back. I had a few beginner problems, draw in, tension, etc. The process was really exciting though, and this little sampler will be my pride and joy. I've warped enough for five dish towels and left enough allowance for a seam all around. So long as I don't break any more threads I should be fine. Thanks again!
