Operation Write Home has a tutorial and making flowers for their cards. The flowers can't be too 3D or they won't go through the mail without being destroyed. (Thank you postal service!) I made this card using the Everything Elanore stamp set from Stampin'Up! and rolled the flowers to give them a little dimension. I popped them up with a skinny dimensional.
This is a monochromatic card using Baja Breeze from Stampin'Up! I made six of these cards, one to send to Operation Write Home and five for my Swap group.
