Somehow on one baby quilt the bobbin tension got loose when one of my students was using the HQ. I removed the bad stitching and requilted the baby quilt myself. Funny story about this particular quilt. After my student spent hours choosing the right shade and pinks and greens for which she was being paid, she found out the quilt was for a dog. She would have done her best anyhow, but wouldn't have been so fussy about the shades of pink. :lol:
