The inside lining was more of a challenge because I didn't have much in the way of a super huge very soft and thin wool sweater. Rather than spending weeks of daily thrift-store trips, hoping to get lucky (not much selection in this small town), I found the softest large scraps I had and pieced them together patchwork style for the lining. The yellow is a super-soft cashmere, and the black is a silk/cashmere blend (so luxurious to the touch!). All the rest of the pieces are merino wool, also very soft. These are the front & back inside out photos:
