Sears Tower / Willis Tower

Willis Tower (formerly Sears Tower) is an iconic skyscraper located in Chicago. The origami model presented here is made from my Building Block Units (768 × A1, 228 × A2).

This model was my first major folding experience with a bone folder. I bought my first one especially to fold this model since I was afraid that folding almost a thousand units from thicker than usual paper would be a challenge for my hands. I liked using the bone folder so much it became a tool I use almost all the time now.
