I'm making a skirt and a messenger bag using grey canvas and adding some color with pink topstitching using Jeans Stitch thread so the TS really shows. I thought you might like to see the dramatic difference between the Jeans Stitch thread and all-purpose thread. It's pretty amazing!
Here are tips for using this heavy thread:
use a size 100/16 topstitch machine needle - "topstitch" machine needles are marked on the front
use all-purpose thread in the bobbin - this thread can be used, but it's easier to sew with thinner thread in the bobbin
lengthen your stitch to 3.5+
sew slowly and carefully so the stitching is neat and even--any wobbles are going to be obvious :0]
