We’ve all been there. You take your project to go. You say, “nah, I’m just gonna pack my yarn and needles (or hooks)”. Then you get into it and realize you need a ruler or you need to check your gauge because you are not going to rip this out! So, just add this gauge ruler to your keys. You’re never going to be stuck again. On the other side? Well if you’re a swapper and mixer of yarn, this little chart will help you match what weight of yarn goes with which needle or hook. It’s a great quick reference.
