Sushi with Filling
I like this pattern because it's more realistic in the sense that there's actually "rice" wrapped around the insides of the sushi. You can use anything you want for the sushi filling - my family likes putting egg, cucumber, 肉To make egg, or anything flat: ch7; starting with the 2nd ch from hook, sc across (6).
To make cucumber, pickled radish, or anything that's slightly chunkier: ch7; starting with the 2nd ch from hook, sc into each of the back bumps of the chain (6).
To make 肉
For each topping, fasten off leaving a short tail. Knot the starting and ending tails together, and then weave the ends into the middle of the topping (these will be hidden in the middle of the sushi).
