Ok, I've done it both ways now - slipping both sides k-wise and slipping each respective side in keeping with the stitch for that side, either K or P. I'm doing a simple stockinette piece, so of course every other row is P. Slipping pwise on the purl rows does make the braided look, but it has a noticeable purl bump on the braid. Slipping K wise on the purl row just makes a mess. Someone help me~!!!!!
