Pinterest is a dangerous place people. I can get lost for hours finding projects to try. One of the projects that kept coming up was a yarn wrapped cardboard letter. I have yarn and I have cardboard. I like letters. I thought that this would be a great idea to try out. If it worked, I'd have a cute W for my office area. If it didn't work out, it's cardboard that I was going to recycle anyway.
The basic supplies that I saw on all of the Pinterest boards was that you need yarn, cardboard, scissors and/or a box cutter. Don't get caught up in any jagged edges that you might have. As you wrap the yarn around the edges and corners, it will smooth out the shape. And, don't get caught up in making a perfect letter. It's a creative piece that you will enjoy making and enjoy looking at.
You can begin wrapping your yarn around the letter. You can use 1 skein of yarn or 5 skeins. It's up to you. I chose 2 because I liked the colors. I duct taped them to the back of the letter and began wrapping.
