I have an HQ Avante and have been trying to help a friend to quilt her baby quilt using minky on the back of the quilt, cotton batting in-between. We have adjusted how tightly rolled the quilt is and the stitch length as well as the side tensions and put in a new needle. Although the stitching looks good, most of the stitches have minky pokies on the quilt top. It has the look of using a contrasting color on the back and the top tension too tight if that explains it. However, what we see is the minky, not the thread. Any suggestions?????
