I made valentines last year for William that turned out ADORABLE! This year I was seriously lacking in ideas so I decided to just take William to the store to buy some. While we were at the store, I was so annoyed about how cheap the valentines were - they didn't even come with envelopes. While we were there I was looking up supplies for another project and my sister posted a tutorial for these cute Star Wars valentines (he wanted the Star Wars ones at the store anyway) and I found my solution!
