Cute DIY pillows! Love love love. - these are not DIY, though maybe you could. they are handmade, by a seller on Etsy (who I've linked properly). warning though, there is way too much cuteness in her shop!
Totally cute idea... And pretty simple! The illustration doesn't say what size paper to use, i tried 12x12 first and it didn't work right, cut it down to 6x6 and works perfect for a little box to put a trinket in or something small and personal =)
