DIY Tissue paper Garland Crown. I love the flower crown for the littles! What little girls wouldn't love to be a fairy princess...and it's and easy diy so you can make lots of colors!
The National Garment Cutter Book of Diagrams - lots of patterns to scale up.... Not really "retro"... more vintage, but still fascinating! Probably too difficult for me, but what a great reference!
