This hamburger is crocheted in one piece, in only 24 rounds, with no sewing except for adding optional “sesame seeds” to the top bun.

Any weight yarn will work as long as you have the correct sized hook to match the yarn.

Note: your lettuce will have 8 scallops, but the one in the pattern photo has only 6. This is an error on my part because I messed up the counting as I was testing the pattern and had to adjust on the fly.
