My old cabbage patch clothes pattern was one that my aunt created on tissue paper from an infant dress and pair of pants (like the old rubber pants cover ups with ruffles on the butt.) and each one had a matching bonnet. And then I copied her pattern onto news paper. I just got a little creative like you and added different embellishments. I made my own pattern for a pair of long pants, and then I added a bib to the front and shoulder straps to the back for bib overalls for her boy doll. Gee I had forgotten all about that creative talent I used to have.
This year for one of my DGD's Christmas presents, I have taken her mommy's (my DD) baby doll cradle and made a new mattress pad and pillow along with a quilt w/a matching pillow case. It came out so cute. I will definitely have to dust off my doll clothes making skills. And see what I can come up with.
