I’ve always thought of a D12 as the damage die I aspire to. Warlocks typically do a D10 of damage, but even a D10 is often aspirational to Bard-me. A D12? That’s some Barbarian damage.

Note that this pattern has options for different sized squares by using different weight yarns (sport, fingering) and corresponding needle sizes (3.5 mm, 2.75 mm), as well as both knitting and crochet instructions.
