Store your patterns in 9″ x 12″ manila envelopes.
Being able to get those blasted tissue paper patterns back into their original envelopes is an admirable skill. We’ve decided it’s not a very marketable skill however, so we just don’t bother trying anymore.
We use manila envelopes instead. We cut up the original pattern envelope and tape it to the outside and then put the pattern pieces inside. It’s also easier to store patterns this way as you can get filing boxes for the manila envelopes.
