That annoying hump in the middle of a room after stretching
I always had trouble with a slight rise in the carpet center after using a power stretcher. Started marking the plywood subfloor seams with chalk before laying the pad. Now I can avoid placing tack strips right over them, which stops the bulge. It's a small step that made my stretches way smoother.

Oh man, that chalk trick is smart. I fought that same hump for ages. @miataylor is right about the pad bunching being the main issue, but your fix makes total sense. If the strip hits a seam, it just pushes everything up. I started using a knee kicker right on the seam line first to settle it down before the power stretch. Those little things really do add up to a flat floor.

Honestly... I've always found that bulge comes from the pad itself bunching up, not the tack strips. A smoother pad makes more difference for me.

Totally get what you mean about the pad bunching. I had that happen with my last quilt, where the batting just would not lay flat no matter how I pinned it. A tighter, smoother pad made all the difference for me. Stretching it really taut before basting helped stop those little wrinkles that turn into bumps. The strips can add pressure, but a lumpy pad underneath is the real culprit lol. My quilt shifted less overnight once I focused on that smooth base layer.

My third quilt failed until I took miataylor's advice and finally smoothed that lumpy pad.

Chalk lines are a game changer for that. Also found that a quick pass with a seam roller over the pad before the final stretch can work out a lot of those little bumps.
