What I do is to first put Contact Cement on the Shroud and also the Futtock Stave, which is basically a cut down Toothpick.
Once make contact, I use my Tweezers to get to spacing right. The Contact Cement has just enough give so I can adjust it. Once I get the spacing right, it’s just a matter of squeezing the 2 sides together. After a hat I drop some Superglue on it to fix it in place.
I ended up using a double binding for the Catharpins. it’s a challenge doing this in an enclosed area, but I’ve tied so many Clove Hitches, that it’s second nature now.
