My 14 inch (with 3" corners) came out to 5x5. I did a 12 inch (2 1/2 " corners) and it is 4 1/2 x 4 1/2 and my 10 inch
(with 2" corners) ended up 4 x 4. Tacking down the corners and putting on the buttons is what takes all the time. I am going to make a few boxes to that point and then sit down one evening and do the hand sewing on all of them at the same time. I only put the ribbon on this one because in the end I didn't think that button was the greatest so wanted to jazz it up a bit. I hot glued the ribbon on. It's not velvet, just normal 1/4" ribbon. It came on a roll with 3 colors, gold, green and red and I got it at Michaels.
Have fun with the next ones you make!
