This is a bulky-weight, bottom up, seamless adult hat with eyelet-lace ridges for interest. For real interest, though, the knitter works the hat inside out and then reveals the public side at the end. This construction takes advantage of the easier k2tog and ssk over the p2tog and ssp stitches to make the interesting texture of the ribs. The name comes from a small cactus – actually a cactus lookalike named “spurge” – that I saw at Longwood Gardens while visiting my grandmother. This hat was knit that afternoon while enjoying the early spring Gardens.
