DIY Vest to Jacket Restyle Using Knit Sleeves from DIY People here. There is no pattern for the sleeves but you could use any sleeve pattern on any vest (or chop the sleeves of of a sweater and sew them in). I used Chrome to translate from Danish to English.

DIY Chunky Knit Cable Headband Pattern from Scarffaces here. I love knitting cables because they are so easy to do and look hard to do. This is a really fast project: size 17 needles, super bulky weight yarn (category 6) and using two strands at the same time to knit with. From the comments section on kollobora here by Scarffaces: 

This takes me about 30-45 minutes to complete but I am really speedy. I used two strands worked together of lion brand wool-ease thick & quick, and it uses less than one ball.
