Well done! Using a treadle can be a little tricky but soon you will be a pro. If you are having trouble keeping your seams straight, you might benefit from using a seam curb. I have one that is magnetic but you can make yourself one from a hotel key card or similar. Bonnie Hunter has instructions on how to make one at her Quiltville site. It will be under one of the tabs on the top of the site maybe under tips or misc.?
