Tell us about yourself!
You explained everything very well and I was able to clearly follow your directions. However, though I triple checked my calculations, the bottoms were miles too small for my son. I had to add two 3 inch panels to each leg, and 4 inches to the top of the waist band. And even then, the crotch was barely wearable for him. I added all the seam allowances you indicated. I don't know if it has something to do with the fact that my son has quite a round bottom and thick legs... something wasn't quite right.
