you've got the answer of instructions by adorable appl. already.
Interesting. My problem is finding toppers that fit 4 by 4 hoop.
I don't know the size but here if you scroll through the designs are several free toweltoppers.
On Embroidery Library, they have towel toppers to fit the 4 x 4 hoop. They are not free..but they have a lot of sales if you sign up. But they do them entirely different than these are done. I really like the looks of these, can't wait to try it.
