This quilt top has me stalled out. Original plan was to make a queen size, but then I decided to make one twin size and the other full size to fit beds in the grandchildren's guest room. After getting this one all sewn together I thought it would be a great opportunity to practice my FMQ (which I have never done more than a few practice blocks). I've now broken it down into 3 units so I can quilt it in sections on my domestic machine. But what to do? The pattern is so very busy and my FMQ talents are limited. Do you think I should try to outline the stars and just fill in with meandering. What I have done so far doesn't seem to set off the stars at all and it is "puttsy" to try and quilt all the little spaces around them; my stitch consistency has much to be desired, but it is just practicing and the GC certainly won't be critiquing it. I'm almost ready to go back to straight, diagonal stitches, but that doesn't help me to learn FMQ or perfect any technique. Any advice is appreciated - would darker bobbin thread help?
