I love, love, love Lawn Fawn, definitely on the Kawaii/CAS-side of image design and just my cup of tea. Their blog is great for ideas and for beginners like me. I like how versatile their stamp sets are – this one is from their Critters in the Forest stamp set. I got it with the matching die to get them cut out nicely.
I usually buy them at Oozak (ask for Randy, he’s delightful and easy to work with) or markerpop (they release new products well – look out for promoso). Lawn Fawn stamps are a bit on the pricey, but you’re paying for the cute design work.
