Well done Jenna! Keep it going down, hun!
Sammy, I used a 4mm hook to make the scarf. A lot of patterns ask you to start off a half a mil bigger and then use a smaller one... no idea why, as I'm still learning myself lol. I'm using double knit too, I asked the lady in the wool shop which wool to use and she picked it out -- I just picked the colour -- and she said it was suitable for a 4mm/4.5mm hook. Good job cos the only other size I have is 6mm. I'm thinking I'll go into the shop every week and pick up a new hook and some wool.
I'm going to try working in the round next, as I have a lovely idea for a hat for Fia -- my baby -- for Xmas... a white or cream hat with a red ribbon worked through in a bow, something like the scarf, but not all the way round as I'll need it to stretch. Might eventually have a go at mittens lol
I would just say be aware of where the tutorial videos you're watching are from, as American crochet and UK crotchet differ in the names of stitches. E.g. a single crochet in the U.S. is a double crochet in the UK.... I had to convert the scarf pattern from U.S. to U.K before I started.
