Today I choose "Football". My husband and I are not fans at all but yesterday we had a visitor who is and as his Grandson is soon to be 11 and doing a lot of training for the under 12's I thought it appropriate.
I used my Cricut cartridge "Soccer" which is brillant for these sorts of cards cut the image from black pearlescant card - 3" high and shadow added a football embellishment and printed Happy Birthday.
This is version 2. I have draw a fine line around to frame it. Thanks Chrissy for the tip. The sentiment is done with my design runner. Font is Chalkboard.
