Step 2: Piece It Together
(CLICK FOR FULL-RES)
As if assembling a puzzle, nudge and rotate the pieces into place. Select a segment’s layer, then tap the V key to activate the Move Tool. Tap the arrow keys to move segments into position. To rotate the parts more accurately, choose Edit > Free Transform and move the pivot point (centered by default) to the corner to act as a fulcrum. Then grab the opposite corner’s Transform handle and rotate the piece into place.
