I admit, this took me about three weeks to do. I'd do a letter or two each night when I had time. It's a craft that needs to be saved until after children are in bed because rambunctious 18 month olds and mommies with needles in hand is not a good combo.
But, it was super easy.
I spent a little time on Word searching for a good blocky font. I chose super basic Arial Black, used all caps and bolded it. My font size was 330 pt. This meant I could get 2-3 letters per page. I printed them in a light gray so I could just see them to cut out and to not use up all the black ink in my printer. I did all the printing and paper cutting at once.
I had 9 colors of felt that I wanted to use. I don't think you could have 26 different colored letters, but I could be wrong. To cut out each letter, I taped the paper letter to the felt. I even used more tape than necessary because cutting through the tape ensured that I was cutting good lines.
Three weeks later, I finished up my 26 letters. Are they perfect? Heck no! But they still look pretty darn good. And E won't know any difference.
Then, in a fit of craft craziness. I decided that he needed a bag for his letters. So, this happened.
And it holds his letters perfectly. The square on the bottom is 5in x 5in and it's about 7.5in tall.
Best of all, this used eleven 8.5x11 sheets of felt. At $0.25 each, that's a whopping $2.75 in felt and maybe a couple dollars worth of embroidery floss and poly fill, but I actually already had that stuff. Compare that to at least $30 for a set of letters on Etsy. Blam!
