Hi all you terrific quilters! I just started quilting about a year ago and I thought it was time I started on a "project". I'm making a twin size throw for my daughter and I'm having trouble with my beginning and ending stitches. They're unraveling! I find myself doing a back stitch and I know you're not suppose to do that. I start my stitching by bring up the bottom thread to the front. And I'm not really sure how to end the stitching. What am I doing wrong?!
