Garter stitch knitted in the round

I have knitted sleeves on a baby sweater on 4 dp needles - top-down. I need 6 rows of garter st at the wrist end of the it possible to do garter st in the round? The sleeves were done top-down in stockinette st so I purled around the 6 rows thinking that would make garter st but it is just purl with the stockinette on the reverse side so, of course, it rolls to the inside. Can garter st be done in the round?
