I’m a new knotter and am having problems with an abbrevation. Can you please tell me how to do k2sp.

Thanks, Di

Found this explanation in a Berroco pattern:

K2SP
K2 tog, then sl st back to LH needle, lift 2nd st on LH needle back over returned st and replace returned st on RH needle (2 sts dec’d)
