omegabeth pointed me towards
Stitches, Needles, and Guns (glue guns, I think) craft fair that the Central Mass Derby women are putting on February 6. I think I can make this go. I've got a great bit of product set for Arisia, and I've yet to sell more than 5 pieces there, so safe to say I won't have to do much replacing for this, although the skull & cross bone quotient will go up by a large factor. I also am waiting to get some new clay molds from a helpful vendor from the last con I went to- they're supposedly also a bit macabre/steampunk. I just hope those arrive in time for me to incorporate in for the Arisia show, too.
More on this later after I confirm no really I can do it and have sent in my money.
