I love vintage patterns! If anyone is looking to buy vintage patterns, check out your local resale shops or go online to www.etsy.com , you will find tons of patterns on etsy.
Not only can you use the patterns to make clothes, but you can also scan the front of the pattern envelope and clean up the image and remove things from the image and turn it into some cool gift tags or some other art project. Always think outside the box...or in this case, the envelope.
Happy pattern hunting!
