Our guild makes a quilt that we raffle (every two years) and donate the money to a local women & children's shelter. We also make a quilt for a homemakers' group that they raffle (every year) and donate the money to charity.
Several of the gals make Quilts of Valor. I made a top once that another gal machine quilted.
Recently, we have taken over a project that supplies blankets/quilts and other personal items to children who are rescued from meth homes. I made a baby quilt last month for that.
I don't have alot of time to sew, as I have 2 part-time jobs, or I would probably do much more charity sewing.
