Both fabrics are 100% cotton. the top is a slightly thicker cotton and the shorts are cotton poplin. I used the shorts pattern from the Kwik Sew 2811 pattern I used for these pyjamas . They are simple elastic waist shorts so nothing complicated and very quick to sew. I added about an inch to the length of the legs.
The top was the re-fashioned item. I had cut out a kimono sleeved, very simple shaped top and even got as far as sewing up the shoulder and side seams and attaching the neck facings. Then stopped. I just didn't like it. Sometimes you just get that feeling, don't you? I then shoved it in my sewing box and left it, waiting for inspiration so I could decide what to do with the fabric. Then the pyjama inspiration! I took the partly finished top and cut out a New Look pattern I already own. I can't find the pattern on the New Look website so it's probably out of print now.
It's been satisfying sewing up pjs that I will need and also using fabric and patterns I already have. And I've used an unfinished garment stuffed at the bottom of my sewing box!
