I taught myself quilting several years ago when my daughter asked me to do something for her with her old hard rock cafe t-shirt. I had a sewing machine, and as a teen had made my own clothes . . . So how hard could this be?? I have made about 15 quilts, most are non-traditional but I got tired of paying someone to do long-arm quilting. Then at my husband's suggestion, I joined AQS and a new world opened up. . . FMQ? Different threads ??? And then I found this site. I took a class in FMQ and for someone who never liked straight lines, I found not seeing where I was going quite over my abilities. . . But I am still 'doodling' on scrap muslin and Batting. So here is my question. When you are piecing do you use regular thread or go to size 50?? I need some help here please
