The actual picture unit size is 86 x 108 mm, so you need room for that.

No question about it, the best way to process would be in a Fuji Instax Wide camera; no other camera will work.

It's not impossible to use a rolling pin to get some sort of result, but remember it must all be done in the dark. Your results will vary from try to try.
