Ok a rookie mistake. I ordered studs precut to the height I needed and just finished framing my shop. Got the walls up and it looks good, level and plumb. I go to put OSB and realize I forgot to count the 2nd top plate so the sheathing is 1 1/2" too short. Can I just cut a bunch of small strips to fill the gap and if so is it best to put on top or bottom?

Tx
