The sketch seemed to scream out "pocket" to me so that's what I went with. I sewed 2 pieces of brown cardstock together using a blanket stitch and decorated the front.
Used for the outer: generic cardstock, KI Memories paper (from the Funky Paper Pad - again!), KI Memories ribbons, fabric flowers, button from my box, DCWV alpha stickers, MM mailbox letter, Papermania rub-on, Kay &Co Marcella metal embellishment, stranded cotton. Used for the inner: DCWV cardstock, DCWV paper (from Spring Stack), Studio G stamp, EK Success multi-stamp, K&Co Letters to Go, DCWV alpha stickers, KI Memories ribbons, May Arts ribbon, Papermania brads, black Sakura pen.
