There is a bell Styrofoam ball on Craft King. 2 3/8 bt 2 3/8 I don't know if this will work because I do not know the size of the form needed. I just doubled checked and they have other sizes. Hope this helps.
I agree without the Styrofoam bells what good is this adorable pattern.
I too was disappointed that the basic items weren't available at Annie's. The pattern gave me all the info I needed to locate the materials required. So far I've done the wreath and it looks very good for my first attempt.
Ornament is so cute but cannot buy the Styrofoam bells to do the craft. I do not need the fabric; I have quite a stash here to use up. I have the pattern also. Just need bell forms to complete. Suggest you look into perhaps a pk. of 6 bells sold separately.
