I was inspired by these from Ballard Designs. At $59 each, they weren't coming to live in my house any time soon. But I had linen, and I had a plan!
I have these great magnetic foam letter stamps from here.
They're about three inches tall and sturdy enough that I haven't ruined them yet. And there's a lower case set. I want it. Badly.
I was too lazy to wash brushes, so I pulled out my Ranger Acrylic Paint Dabbers in Mushroom, Black and Gold. Random dabbing on the foam letter gave me a cool, mottled look. I drew a line on my fabric using an air soluble marker, and working from the center out, stamped on my words.
