I have been keeping my cut sewing patterns in gallon size ziploc bags. It works. But it isn’t an elegant solution. The bags are sliding all over. And I put them in a baby wipe carton.
So, I finally bought a box of file jackets. And I’m putting the pattern instructions and pieces inside. And printing a copy of the pattern cover and taping it to the outside. I prefer to print from a .pdf file, because those often have on one side, all the information that is on two sides of a pattern envelope – the yardage, line drawings, and photo. (But not so much this time.)
When I use the pattern, I make a notation on the outside as to what size I’ve cut and what alterations have been made, along with the date. My example is from the fleece pants that I made earlier in the week.
I only have about six of my patterns set up this way. But it’s working well so far.
