This is a story of two pairs of pajama pants. One would get worn all the time and I had to force myself to wear the other pair when the first pair was in the laundry. After many weeks, I put it together: the neglected pair had no pockets! This is something we can fix!
Something about me: I hate pajama tops. Why bother to button up a shirt with a collar when you could just toss on one of a thousand free tshirts that you love? I don't even like the way the top looks when worn with the matching bottoms.
All this is to say: the pajama pants that I love conveniently came with a top that I decidedly would never wear. This top provided me with the perfect material out of which to make my pockets. If you are an individual who loves to lounge around your fireplace, drinking cocoa out of a mug in your matching pajama set, you can just make your pockets out of any old fabric. Be warned, however, that you will be able to see at least a little bit of the material inside the pocket most of the time when you are wearing your new pants, so choose a dark or matching color.
