I was just asked to review this question, in which user 'Johannes' is attempting to make a canonical question on beginner's knitting mistakes.
In its current state I think it's too broad, and have VTC'd as such, but the idea itself is a good one, and since we don't seem to have anything on Meta about the topic I thought it would be good to discuss it.
Should we do canonical questions on Arts & Crafts?
I feel like some well chosen canonical questions would help deal with the large number of fairly basic questions we receive.
There's room for discussion on the exact form they could take, but the 'standard steps towards a canonical question' over on MSO seem like a good starting point.
