I saw one a pastry crust bag on the King Arthur website yesterday- they have two sizes- 11 in and 14 in:
If you bake breads or make homemade pizza, I would suggest their Italian flour or their pizza crust flour!
Amazon has the Martha Stewart Plastic 14” pie crust bags for 95 cents.
I actually only remember the old canvas ones, which I guess have given way to plastic.
Yes, that’s it. Super easy to roll out dough.
