They are BIG, and you can put notes, cards, and letters inside. I filled mine with special cards from Nel and Jess, sister, best friend, and a few blog friends.
When I was little, I didn't get that many toys, but my mom did buy me colored construction paper, felt, scissors, glue to be creative and make things. As soon as I got the paper, I went to town making festive cards and notes, especially around the holidays.
I came across this card I made for my dad at 10 years old, and I was surprised that he kept it all those years. I used macaroni shells on it. It's faded and smudged, but it's a part of my childhood, so I'll keep it always.
I think these felt envelopes would be so nice for Nel and Jess to put their wedding keepsakes in. They were only $1, so I may go back and get a couple more.
