I've just started quilting my quilt, the tension is perfect, but the batting pokes through each stitch in the back. I'm using a dark back and white batting (maybe that was my big mistake), but I can't bear to take it apart. Can anything be done? Do I need to change the needle? If so, do I use special needles (my sweet 16 is new to me) or can I use machine needles? If special needles, what are they, what size? Help, please!!!!
