Lace scarf

I am trying to knit a lace scarf. the pattern instructs to k into 2nd stich on LH needle, then k into 1st st. on LH needle, sl both sts to RH needle. All I get is knots. help

It helps if you have loose sts but you just follow the directions. Knit into the 2nd st, then into the first and let those 2 sts drop off the left needle as usual and you have 2 sts on the right needle.
