I always just add fabric on the back side of the needlework or the cross stitch if I add the bell pull hardware. Just 1 or 1 1/2 inch is enough to be sewn together. Then I add the bell pull. Have fun.
I would like to know please what the name of your pattern? Many thanks in advance.

Is there a picture of a project using the bell pulls...What a cool idea.

OK, I saw pics of bell pull projects. I'm new to this, so didn't know what they were. Seems to me it would eliminate having to frame. I'm looking at my mother's old projects, some framed, some not. My favorite one of hers is framed but no glass. It is about 40 years old. Most of her projects have been mounted on board with either staples holding it or heavy threads on the back. Unfortunately, we lived overseas during the time she made stitchings. I didn't get a chance to watch or learn from her.

I would contact customer service as they can get you the interior size for sure. If you click on customer service in the thin brown bar with white lettering at the top of every page on this site, Kristi can assist you!
