Gnome's Mitten in the Rounds

Knitting Techniques used:
- the Thumb method Cast-On
- knitting in the rounds with two circular knitting needles (My needles are different colour, just easier for me to pick up the correct set to knit.)
- three needles bind-off

Crochet Technique used:
- Chain Stitch

I knitted as per instruction, with no reduction in stitches (see more detail notes on boots).

Place a slip knot with a long tail on the needle. Hold the tail in your left hand and wrap it around your thumb. Now, knit into the loop of the left thumb from front to back.
Knit 12 stitches. Move the stitches to the right side of the circular needle. Transfer 6 stitches to the second set of circular needle. Fold the stitches ... and start knitting in the rounds. I did only a few rows to show the arm. When you are ready to change color for the mitten, make sure you leave a long tail of the yarn used for the mitten, about 6 inches long. You have done 4 rows for the mitten and are ready to cast on 4 stitches at the beg of next 2 rows for thumb. Find the long tail yarn and fish it out from the inside and hold it above the mitten. Use a crochet hook 1mm size smaller than your knitting needles. My knitting needles were 3mm so I used a 2mm crochet hook. Place it in between the two knitting needles and push it through below the highest connecting yarn. (Double click on the picture to have a better view)Use the hook to grab the tail yarn and bring it through to the outside of the mitten.
Make 4 chain stitch and fasten off the tail yarn. Back to knitting. With the 4 crocheted chains on your left hand, use the knitting needle to pick up 4 stitches. You have cast on 4 stitches, one from each chain stitch.Now turn the work the other side and use the second set of knitting needles. Use the right side of the circular knitting needle to pick up 4 stitches from the other end of the crocheted chains. Knit across to the end of the grey needle and knit across the silver needle all the way including the extra 4 from the crocheted chains. You have cast on the thumb. Knit another round. This complete the cast on 4 stitches at the beg of next 2 rows for thumb.Carry on with the pattern knitting in the rounds. When you are ready to cast off 3 stitches at beg of next 2 rows, move the work to the wire and turn it inside out, and cast off 2 stitches using three needles cast off method. (Note: the mitten is small, so it is tricky to turn it inside out, needs patience)Now turn the work right side out, you should have 7 stitches each on the left needles and 1 stitch on the right needle. Transfer that 1 stitch from the right needle to the left needle that's further away from you. You should now have 7 stitches on the grey needle, 8 on the silver. Knit a round to the last 2 stitches and knit the two together. 14 stitches. Knit one more round. This completes the cast off 3 stitches at beg of next 2 rows. Continue knitting in the rounds until you are ready to cast off.Move the mitten to the wire, turn it inside out and use three needles cast off all the stitches and fasten off. Turn the mitten right side out and a cute little seamless mitten appears.
