I found a frame at Joann's for $7.99 and I had a 50% off coupon so it came to $4.00. For the frame and the 4 x 6's I printed, my project cost less than $6.00.
Pretty good price if you ask me! Let's hope my husband likes it too. ;)
edit: I lied. I forgot about the letters. They were $1 each so I spent less than $8.00 total. Still pretty good on the budget.
