I want to show how I cast on stitches for starting to knit my toys.I make it with crochet hook.
At first make a simple loop of yarn.
Then insert a crochet hook through that loop and grab the yarn and pull it through the loop. Then draw another loop through this loop on the crochet hook. We have one stitch. Repeat until you have all the stitches you want. Usually I start to knit toys with 6 stitches. Slip the stitches from the crochet hook onto your double-pointed needles. Pull on the short end of the yarn to tighten the loop and close the circle. And continue to knit as usually. I hope that it will be helpful for you 8)))
