Inspiration: sweater peplum

Now here's an idea: Add a peplum to a sweater that's just a touch too short, a la the tutorial by Jessi over at Adventures in Dressmaking. I'm thinking of one purple sweater in particular, which is really nice and fits great except for being just a touch to short, so if I take a deep breath you can see the tummy. I'm a touch nervous about mixing a woven with a knit, but if done right, I think the gathering should create enough give in the peplum.

I'm still not sure I can get on the embellished knit bandwagon, but if I can salvage a nice sweater... it may just be worth a try.
