Well I have my first and only Tee shirt quilt made and my DH has it on the quilt frame and he cannot seem to get it quilted. He has tried everything you would normally check, like tension, needle, cleaning bobbin etc. The thread always breaks. I am wondering if it could be because of the knit of the tee shirt and if there is a needle one could for quilting on knits. I have run out of ideas of what I thought could be the problem. He is very patient and has ripped it a couple of times and I am beginning to worry because I have volunteered to make it for the boys track team to auction off to raise money for their team.
