Bit of a long shot but I need to add belt loops to a wool coat and I have embroidery silks...I'm sure that back in my friendship bracelet days of the 90s, there was a technique to self-knot embroidery thread to make it thicker - almost braiding it by knotting it on itself. I've googled the heck out of this but got nowhere. It's not cobra knots - I've done that on paracord with the kids - and I don't want the kind of flat friendship bracelets we used to make (much as I love them...). The technique I'm thinking of just gives a slightly thicker knitted cord, if that makes sense. Any advice gratefully received!!
