I quilted this sample with 100% cotton machine embroidery thread by DMC. This is a fine thread, 2 ply size 50 with a soft shine. It is not a strong thread but would be great for quilting a wall hanging or miniature quilt. I used a size 14 quilting needle and a stitch length of 2.0 and 4.0 tension on my Bernina 730 using the BSR stitch regulator.This thread quilted very nicely on the quilt sandwich with 80/20 Hobbs batting. The Bottom Line thread by Superior Threads used in the bobbin matched up very nicely with the DMC thread.
I use this thread I use when piecing my miniature quilts all the time and have several colors on hand. It is also nice for applique since it is a lighter weight thread so the stitches blend right into the fabric.
I would recommend this thread for lightweight quilting. It would be good for background quilting as the thread buildup is not heavy as well as thread for quilting the main motifs.
