Change things up a bit with Jewelry
Do a jewelry swap for those who don't bring the used purses.
You can create separate numbers for the "jewelry" people so that those who brought purses go home with purses and those who brought jewelry go home with jewelry.
For churches with large Women’s Ministries or numerous Women’s Small Groups
If you have more than one small group participating in the Purse Swap Parties, you may want to consider mixing the groups up from time to time.
This will allow the ladies to meet people from other groups and it will also help keep the purses from seeming redundant.
Also, if your small group is meeting once a week, you may want to consider swapping just one purse at a time in order to maximize your time and minimize pressure on the participants to bring multiple purses each week.
