Hello, I just checked the designers website and this pattern is done on perforated paper. Hope this helps!

Yes the designer designed it for 14ct. perforated paper, but you can convert it to any other fabric you want. You can easily use 14ct. Aida cloth. The pattern uses 27 DMC colors of floss plus Mill Hill Beads, and Kreinik #8 metal Braids. Hope this helps.

Thank you! I thought it looked like perforated paper which I enjoy working with. Think I'll order it.

The reason it's done on perforated paper is that it's 3 dimensional. All of the small pieces are stitched separately and then attached. If you were using fabric, you'd have to worry about the edges unravelling. After the stitching is done on the paper, it is usually backed with a heavier card stock paper.
These are super creative, I'm thinking of starting some. Good luck !!
