This hat is in aran (ish) weight recycled plied yarn - a red recycled fuzzy angora blend around fingering weight, plied with a yellow wool recycled yarn around DK weight. (Learn about how to make yarns like this in the Making Recycled Yarns ebook.)
The height is 8 inches, with the brim folded up. This hat used about 109 yards / 100 meters of the aran weight yarn.
This was my first sample of this pattern and I hadn’t totally worked out the best sizing yet - this one has a very loose fit. I ended up writing the pattern to plan for around 4 inches of negative ease, for a comfortable fit on your head; this one was measured on the hat to have 1 inch negative ease, but it ended up having no ease (it’s exactly the same size as my actual head) which makes it fit very loosely. It’s fine, I still like it, but I’m just explaining how it differs from how the pattern is meant to be ;)
When you measure the gauge on the hat (as the pattern is written), it can tend to be a little bit tighter than it will be on the finished hat, which is part of why 4 inches negative ease is recommended for figuring out your stitch count. If I’d used 4 inches on this one, with the slight change in gauge in the finished hat it would have ended up with 3 inches, a good fit (but even if the gauge didn’t change, 4 inches negative ease in a stockinette hat is a fine fit).
