That is to bad. I still hand quilt "just for fun" in the evenings but I've made huge (120 x 120) quilts on domestic sewing machine. Gives a whole wide dimension for quilting designs. Yes, it takes practice but best way is to "jump in and do it." People receiving your quilts won't mind the differences that occurred in stitch lengths. On the contrary, they will be pleased to be included in your "learning curve." Don't give up! Best resource I've found is Leah Day.
