This is an adorable sweater for the man/boy in your life. You can make it in any kind of colorway, and as it is knit in blocks, you could add any or subtract any colors you want.
Make it in a solid and it could go to most offices. Make it in two contrasting tones, and it celebrates the weekend. Make it in the Mr.'s favorite team colors (Red and Blue for the Buffalo Bills) and it's a multipurpose garment. (Warmth and spirit in a handmade. Woo Hoo!)
Make it in a cashemere blend, and it's a luxury he'll never forget. Make it in baby alpaca, and it's warm enough for outerwear, even here in the Buffalo area.
Have fun with it. Take pictures. I'd love to see them!
