I've been experimenting with adaptations to a basic hat pattern for the lovely bubbly Country Loom yarn by Loops & Threads. It's available in so many colours, and I have many of them! It works up super soft, warm and snuggly, and the regular yarn for the brim gives it a nice snug fit to keep your ears nice and warm. The finished result is a fitted hat with a teensy bit of slouch.
Rib is worked on 8.0 mm needles with 2 strands of worsted wool.
Body is worked on 9.0 mm needles with 1 strand of Country Loom super bulky
For small, medium and large:
Cast on 44 (48, 52) stitches. With 8.0 mm needles work in rib for 6 (7, 8) rows.
Switch to 9.0 mm needles and one strand of Country Loom wool. Work in stocking stitch for 14 (16, 18) rows. Decrease by knitting 2 together across, purl a row, knit 2 across, purl a row until you have 6 or 7 stitches left. Cut yarn leaving enough to sew up seam. Thread needle through remaining stitches, gather and stitch up seam to the ribbing. With matching worsted wool, join the seam for the rib, and your hat is ready.
