I'm still having more fun with my wool felt than any one person should have! I'm going to be making a pattern for these pin cushions and will be offering it on my Etsy page.
One fun thing I have learned is that ground walnut shells make a great addition to you pin cushion. Putting fiber fill toward the top and the shells at the bottom gives it weight and a nice feel. You can find the ground shells in the pet store in the bird section.
