Remember stickers shrink just like your slabs/rough lumber. Set the in the same orientation and flip every few months. I made that mistake and had to turn my black oak slabs into turning wood... actually not a bad mistake, made a chess set. Now the maple, oak and fir are stickered w old dry pine "still wood". If you are in a hurry cut 2x2 sticker, leave it by the fire, dry it in a night, send it through the planner, and/or draw knife, get it flat 1x1. should hold true if milled w grain. In my limited experience.
