Here is one done in the hoop. Hugs. Nan
I had a look at my designs and I made some 3 years ago. They can be made flat in one hooping or with a shaped back, which needs at least 2 hoopings.
First picture shows a flat one in 5x7 format, the second shows the combined patterns for a larger one with shaped back.
When you google ITH frog bean bag a long list appears. Here's a link to one of the sites that came up.
Those are either PDF sewing patterns or they are finished products people are selling. I would like a digitized version. Thank you for looking. I have already searched the internet with no luck.
I wonder if Engineered in Stitches by our Sue Dewsbury might have one. (This is vague in the back of my memory.) Unfortunately, I don't Facebook to check.
