Most of the patterns I've used have a....
Row 1: slip first stitch purlwise, purl to last stitch, knit last stitch
Row 2: slip one purlwise, k1, slip one purlwise, k1, repeat to end
In other words, on row 2, you are moving the yarn to the front for the slip stitches and to the back for the knit stitches. I have not had a problem with it being too tight this way. You might want to give it a try.
