I’m a Fan! Dog Sweater - Knit Pattern

With the I'm a Fan! Dog Sweater pattern, my goal was to design a customizable sweater that can be knit at any gauge to fit any dog, using Izzy Knit's exclusive RUFF+TUMBLE DK (or another DK weight) yarn.

The sweater, itself, is an easy knit. The stitches are simple: K, P, M1L, M1R, k2tog, SSK, K1f&b and German short rows. What might be intimidating is the math. But trust me when I say, you can do it! Armed with a calculator and the step-by-step Recipe Worksheet included with the pattern, you’ll have all the tools necessary to successfully knit a customized sweater for your furry friend.

You’ll learn the most about customization if you do the math yourself; however, we also provide links to the Recipe Worksheet online, either as an Excel file or Google Sheet. These spreadsheets will do all the math for you!

Available in PDF format OR as a printed pattern. (PDF will be emailed separately.)
