Anyway, my initial idea was to buy a punch or two and try them out on the felt. But the ones for paper can't be used for fabric and the general problem with punchers is that you can't reach the center of a larger piece of material (does anybody know of a pattern puncher that can do this? I guess it needs to consist of two separate pieces...).
In the end I turned to the way they did it in the pre-consumption era: Made some good old templates out of cardboard and then happily stitch away. I didn't know embroidery could be so much fun. I do have a couple of fár to big cross stitch patterns, which are wáy above my level and patience reserves. But I always get stiff shoulders, a sore back and teary eyes so I try to avoid falling into that trap. This small free hand stuff however, seems to be just right for a person with the attention span of a fruit fly. Now that they are ready, I'll stick them on some fresh fabric and swirl them in the mixer until they turn into cute bags. Shouldn't take more than a minute, I think. I'll eat a pear in the mean time.
