If you are in a rural area, some women have chores to do that keep them away from church attendance, but they may have time in evenings or afternoons. I suggest you put a notice on a bulletin board at local feedstore, grocery, etc.
If you are urban, find a laundromat, variety or any local bulletin board. Some newspapers offer free space for " community events"....have a " sew in", list types of things being made, then put on the coffee & set out the cookies! You may find some will want to return.
