Diaper-friendly pants

I saw photos of some cute toddler pants on  Mairuru's blog and immediately thought that would be a cute gift for a friend of mine who had a baby girl this year. The bum on these pants is so big, that diapers should easily fit inside...

I didn't have a pattern, so simply eyeballed it and then fixed it where necessary (my original estimate may have fit a giraffe baby, the legs were much too narrow...).

I also used a draw string instead of an elastic so that the pants can grow with the baby.
 

I hope the pants fit, maybe I will have a photo of pants+baby to post!

Happy New Year!
