So... it turns out I didn't get enough twill tape -_-
I got it online from a place that only sells 1/4", 1/2", and 3/4" widths of twill tape and here I thought, "Alrighty, I'll get 2 yards of 1/2" and that'll be enough..."
Nope.
So I ordered 1" twill tape off of Amazon, and I think it should be enough, especially considering how it comes in a freaking 10 yard package.
^_^
Oh, btw, I also feel the need to tell you guys that my supply list from my last post was missing one very important item.
I ordered a Sluis Withof bobbin lace manual from Anneke Rejis!
