Cardboard Loom Woven Hat Tutorial ❄️ Here's a full tutorial for weaving a winter hat on a cardboard loom! To find the correct size of cardboard I measured the head circumference I needed for the hat, divided that number in half and added 2 inches on both sides. I used that number as the length of the flat part of the cardboard. The woven fabric doesn't have much stretch to it, so add a couple extra inches around the edges to allow for the seam! #kidcraft #easycraft #cardboardcrafts #diygift | St
