CustomFit is a website that creates sweater patterns based on your (custom) gauge and size. For the many designs that are built directly into CustomFit, CustomFit will produce a single pattern written custom for you.

For some sweaters, like Afterlight, CustomFit can’t quite get there. Making these sweaters with CustomFit requires more work, which I call “mashing up” the original design with a plain CustomFit pattern.

I do not recommend that you start using CustomFit with a mash-up. However, if you’d like to make an Afterlight-CustomFit mashup, I’ve created a free Mash-Up worksheet to help you do so. You can get it by clicking here.
