You should always place the panels tightly edge to edge, not overlapping. Our wallpaper is printed in one continuous piece and then cut into panels, so everything aligns perfectly for a seamless result.
Be careful not to stretch the wallpaper while applying it. This helps prevent gaps, as the material will naturally straighten itself while drying.
If you prefer not to deal with panel alignment, you can choose MuralTex. This wallpaper comes in one single piece, so there are no seams at all.
