These were made in size 40. Darth Monkey asked me to make cactus pants for her teacher. I decided to try the pattern out on my daughter first and she chose this pink and purple tie dye double brushed knit fabric (from califabric.com) which is super soft and similar to the cactus fabric (from fabric.com). I changed the drawstring waist band to an elastic band on my daughter's pants and a simple yoga band on the cactus pants.
This is the first time where I have made something for someone else without taking any measurements and I made them in my daughter's pants size 40 and I hope they fit well. I do like the pattern and am considering making them in my size (much larger than 40).
