I’ve used this pattern, Simplicity 8268, 7 times now, and somehow can’t get the hang of cutting both of the cuffs so the pattern will be right-side up when sewn on! At least I got one of them on this pair! These are hanging around the house pants, so I didn’t let myself get too worked up over it and I didn’t bother to even try to pattern match.
This pattern has nice, deep pockets which is one reason I keep coming back to it. I try to add a button to the center front of the waist so TheMisterT can find the front in the dark, but forgot to sew it on before I wrapped it! It’s taped to the package under the ribbon.
I bet she would! This pattern is specifically for knits with a certain amount of stretch, but I’m sure there are similar patterns or more-skilled sewists who could make flannel work if you wanted more flannel.
