I deviated from this bottom up cardigan pattern a bit because I was worried about running out of yarn. I cast on 74 stitches and knit the bottom first. When I reached the armpits of the sweater I decided to continue with the yoke and leave the sleeves for last. To do this I cast on stitches for the sleeves using a provisional cast on as follows: k18, sl4 to holder (reserve for later), provisional cast on 27, k28, sl 4 to holder (reserve for later), provisional cast on 27, k18. I then continued to the neckline, skipping the buttonholes. For each sleeve, I picked up the stitches from a holder and the provisional cast on. I then knit the sleeve in the round to the cuff, ending with a garter stitch band. Repeat for second sleeve. No seaming is required, just weaving in the ends.
This is an adorable little sweater and I recommend this pattern. It was very easy to use with any yarn, as long as you're not too concerned about sizing.
