Take my child for instance, the last pair of successful leggings I made took about 4 attempts and the morphing of 2 patterns and 3 different sizes. I was asked to pretest these and cut size 3 width with 2 length and they are spot on!
Then I had a play with the shorts version with ruches sides (sorry she wanted to pose).
Another point to note is that the tutorial is excellent. I have made loads of leggings but even if you have never sewn knits you could sew up a pair of these quickly using the very clear tutorial. Yes I have a serger but you don't need one. I must say that with one though I whipped up the black pair in 20 mins including cutting time.
So there you go, another fantastic pattern, well done Lydia.
