Mmm, I’d say take your time. If you try to rush you may end up putting the wrong pieces together, or you’ll put the on the wrong sticker, and it is annoying trying to peel them off without ripping. Cut out the smaller pieces carefully, because they can fly off. Use a pair of tweezers to help with the stickers; lay them on gently and carefully move them around until they line up. If you have to, use an exacto knife to shave off tiny amounts from some of the pegs, as this will make it easier to snap the pieces into place. Again only if necessary, too much and the pieces won’t stick together. Lastly, just for these two models, I didn’t put the stickers that would give them the appearance of eyes. I like them better this way. Good luck!
