I am making the tree of life pillow by Ladyship Designs. the technique for T2F says, "slip next 2 sets. onto cable needle. purl one from left needle and k2 from cable. for T2B it says slip next st onto cable, k2 from left needle and purl one from cable. looking at this tread, it is always one stitch not 2. i have redone this part of pattern over and over and it doesn't look right. do you think there is a typo and it should read one stitch not 2??please help!
