No, not that kind of nightcap.
A while back, Mamaw gave me some knit fabric. I realized that Malachi is low on pajamas and decided to make him a pair out of this fabric, but it really wasn't quite enough for both the top and shorts. I told Malachi what I was attempting, and he said he wanted a nightcap.
I don't even know where he heard of a nightcap, unless it was in The Night Before Christmas, and it's been a long time since Christmas. Anyway, I recounted that I only had a little of this fabric, but maybe I could make him a nightcap later. He said, "Just make me the shorts and a nightcap." He was pretty determined that this fabric was perfect for his cap, so I did what he asked.
