DIY Textured Cardboard Letters

"Last Thursday , when I was checking some craft ideas over the internet I came across a Pistachio Shell flower wreath by Kelli from Craftshack. She used a textured letter "S" in the middle on the wreath. I liked it very much that I clicked her blog link to check how she made it. She has explained that she used a textured copper backsplash and covered the cardboard letter. I was like I need those letters and suddenly remembered a post that I saw two years back where corrugated cardboard is used to make beautiful picture frames. So, I combined those two ideas and came up with this DIY textured cardboard letters to decorate the small space between the pegboard and the ceiling in my craft space. Let's see how."
