I've been working on this pattern for a while, now. The Waffle Stitch Potholder was based on my swatching for this pattern, and the video tutorial for the potholder also applies to this pattern.
There are lots of waffle stitch hat patterns out there, but this one is work from the top down, increasing in pattern. If you are comfortable seeing your stitches and with post stitches, it shouldn't be too difficult. I love how waffle stitch creates a strong, all-over pattern, but is still sufficiently understated to be unisex or to pair with variegated yarns. If you have trouble figuring out the increases from the written instructions, head over to the tutorial on YouTube (there's a link to it in the pattern too).
Since waffle stitch produces a pretty thick fabric, I made these hats in fingering weight yarn and used a size G hook to produce a texture and drape I like.
This pattern includes instructions for three sizes (infant, child, and adult), and the brim is tacked up in the final round.
Normally, I provide a PayPal Buy Now button in these posts, but I'm having difficulty with PayPal right now. Instead, if you want to buy this pattern, follow the link over to the Stitch Whisper Designs Etsy Store listing.
