DD’s Mom’s group at church makes quilts for children in homeless shelters, picked up by CPS etc. They fold into an attached pouch that makes a pillow.
When I was a kid every woman of the parish belonged to a Circle, all those in a given neighborhood. The Circle meeting each week or month was a big deal, sometimes the only time they got out. They prayed the rosary, and this was the group you called when mom was going to the hospital to have a baby (which happened quite a bit back in the era of large Catholic families), there was a death or illness in the family, they cooked food for funeral meals, or meals for families where mom was in the hospital. One year they came and did housework for us while my mom recovered from a miscarriage. This was the group who came and said the rosary at the funeral home.
In our neighborhood they also had an informal used clothing/school uniform/sports equipment exchange & recycling system going on.
I used to run a hot meal program in former diocese, was responsible for one day a week, and our volunteers rotated, one group was a local MOMS from our parish.
we also had a Seniors group that knit hats for newborns at local hospitals, these have become highly prized souvenirs.
DDs MOMS group became the nucleus for a parish pre-school program. Each team volunteered once every 6 weeks, so that every week preschoolers could have their own teaching and activities during or after Mass. Several times a year the priest said a Mass just for the kids. My grandkids all learned about the Mass in depth long before first communion this way.
