Check the listing for details. Security Envelope Print Pattern Starter Collection 28 Unique Scrapbooking Pieces. Condition: Used. Listed at 25.00 USD. This is a collection of 28 unique security envelope pattern swatches for you do with your heart’s desire. There are 28 patterns, but 29 pieces total since I put two pieces of the funky swirly blue into each. These pieces are cut from real envelopes, so their shapes and sizes vary. I tried to make them as even as possible between the 3 groups I’m selling. Note that because they are from real envelopes, there will be some seams or torn edges or words on the back. I estimate the smallest piece is approximately 2” x 2”. I left them in these differing sizes so you can cut them down however you’d like. This is a great starter collection, or good for scrapbooking and collaging.This is a collection of 28 unique security envelope pattern swatches for you do with your heart’s desire.
