Blocking a purse?

Are you supposed to block a purse and if so, do you just wash it and lay it flat and make sure it measures what you want it to be measured?:shrug:

Yeah, that’s basically all you need to do, though it’s not as crucial as blocking a sweater that has to fit a certain size. Depends on the yarn though - if it’s acyrilic you won’t be able to stretch it beyond its knit size.

It is acrylic so, do I need to block it?

Nope, just wash and dry it. If you try to block it by steaming, it would go limp and the sts relax. You want nice firm sts so it holds its shape.
