Each sewing pattern ships in an acid-free, buffered envelope with an envelope sling to protect the contents and make them easy to remove. A color photocopy of the front of the pattern envelope is affixed to the front of the envelope with archival acid-free PVA.
I'm happy to answer any questions about my store or any of the items here; happy too to adjust shipping, especially if you buy 2 or more. Please convo me!
