We were talking about his over there~~~~~~~~~~ but I had mistakenly use tex 24 in heavy canvas washables, only to find out it works fine, wraps quantity on my bobbin for fewer changes, and makes a small puncture to hide well.
Then everyone pointed out my mistake, that tex 24 isn't supposed to hold. Still scratching my head. I've done it for six years and 4000 yards of canvas.
Maybe this is like the problem I had switching finally to mollies from plastic anchors, it worked well enough for 13 years untill I had a huge catastrophy.
