I've been working on a set of summer suncatchers, this little guy is the first one! It's very easy to make. The download comes with SVG and DXF files to use with a cutting machine. There are also PDF and JPG files for printing and cutting by hand. The crab and "window" shapes are easy to cut by hand. I cut the crab from card stock and the window was cut from contact paper. In this version, I only cut one window piece, since it was covered with tissue paper. If I had used glitter or sequins, I would have cut two window shapes (mirror images of each other) and sandwiched the decorations between them so they'd stay in place.
You can grab this pattern from my Etsy shop!
