If you like sewing, there are so many projects to sew. You said you like making pjs for the DGCs and there are lots of children in the shelters, children's homes, etc that could use warm jammies and even summer jammies. If you don't like to actually quilt, what about making blankets for the NICU unit of your local hospital? They always need them and they aren't difficult to make and don't take a lot of fabric. They actually are a smaller size than the regular nursery blankets. What about doll clothing, such as for the 18" inch dolls (I don't think I could attempt Barbie clothes...that girl is just too skinny...well in most areas anyway!). These types of clothes usually sell well as the "real thing" is so expensive to buy (American Girl, etc.).
Also have you tried machine embroidery? I LOVE it. There is always a market for the little girl jumpers and little boy rompers to be monogrammed. The jumpers/rompers sell in our area for $40-$50 and then with monogramming can be $60 to $75.00.
Just throwing out some ideas...we don't need any more of us going crazy!!
