I cast on 20 stitches on 2 needles following this video tutorial, knit 1 round, increased on 1st, 10th, 11th and 20th stitches, knit 1 round, increased four times again, knitted halfway up the pod, cast off half the stitches, provisional cast on same amount of stitches and carried on knitting in the round till it was big enough, then decreased 4 times each round for 2 rounds, knitted 2 more rounds then grafted remaining stitches with kitchener stitch at the top, cut & weaved in ends. Picked up from provisional cast on and straight knitted a few rows in garter stitch, cast off then sewed the sides down.
