Can one wash graphite out of felt?

I’m working on a last-minute Christmas project that involves cutting shapes out of white felt. However, dummy that I am, I did all the pencil lines on the side I was hoping to have exposed (all they had left was patterned felt, so I was going to use the back). I’ve been unsuccessful with the eraser, but I’m hoping that maybe I can wash the graphite other, either by hand or in the machine? The shapes are small so I worry about warping or shrinking them.

Any tips?

Thanks!
