I'm happy with the way these turned out.
Primary colours are easy to use and with Lego as the theme it couldn't be simpler. The blocks were made using a 1 1/4" square punch and a 1/2" circle punch. I used Stampin' Up!'s letter and number dies. The "is" was made by inking up the word with a marker - it's from a saying stamp that's long-since retired.
I also decorated the envelopes because You should never have a plain envelope!
Now, I'm off to make my shopping list so I'm ready when the Retiring List is released tomorrow.
