Hacks

I made an  (see below for link to the pattern) for my dad and while I was making it found a few hacks to make life (and knitting) easier! The hat has an interesting construction with a two-layer brim, making it extra warm. The pattern has you turn the brim over and seam it down, which is the kind of work I find a bit tedious, so I made a few changes (see video):

1. I used a single strand of Double Knitting weight Yarn
2. I used a provisional cast-on (I prefer the crochet cast-on)
3. When I was finished knitting the brim I picked up the provisional cast-on, put it on a spare circular needle, folded the brim in two and knitted the stitches from both needles at the same time.
