Anyway, it's finished now, and I am already onto something else. I think I may let these little spiders a rest for a while.
The book mark itself is worked in Guttermann Sulky 30 thread, with a gimp down each side of Guttermann Quilting cotton in a double strand of plain blue. It's difficult to see in this pic, but it's there, and a little thicker and more noticeable than the last attempt. The quilting cotton was a bit tricky to work with, but we got there in the end.
I've been keeping track of the hours it has taken me, and I have worked out this book mark has a value of $200. No wonder I only give my bobbin lace to people who appreciate it.
A new book mark has already been started, another deign with no spiders, just seven little tally flowers. I've tried these flowers before and they certainly were a challenge. Oh well, practice makes perfect and I am always up for a challenge. Watch this space!
