Little yellow pants 1986 by Speattle
Probably a stretch and sew pattern
Made for my Daughter in 1986. These are yellow sweatshirt fleece and a simple sweat pant style, gathered with an elastic casing at the ankle. There is a cute shirt with a strip quilted front that goes with it (and she is probably wearing it under the cardigan, but I don't know if I have a photo of it.
In the second photo, my daughter's baby, AS, is wearing the same pants and the little shirt I made back in 1986!
