Confirm that the wallpaper is a half drop repeat, note the full repeat and the stated shift, and check the rolls before cutting.

How to Hang Half Drop Repeat Wallpaper
In this Arte video, you can see how a half drop repeat — also called a half drop match — is planned, cut and hung so the pattern shifts consistently from one drop to the next.

What Is a Half Drop Repeat?
A half drop repeat has a regular pattern, but the design on the next strip is shifted vertically by half of the full repeat. As the wallpaper moves across the wall, the matching point alternates between two positions.

Simple way to think about it: drop 1 and drop 3 follow the same pattern position, while drop 2 and drop 4 follow the alternate half-drop position.

Key Steps from the Video
Unroll the wallpaper on a clean surface so you can see clearly where the design repeats and decide how you want the motif positioned on the wall.
Measure the wall height and allow sufficient extra length for final trimming. The source guide uses at least 5 cm at the top and bottom as its example.
Lay the next length beside the first and move it until the pattern aligns at the half-drop position. Make sure the finished drop is long enough before cutting.
Match drop 3 to drop 1 and drop 4 to drop 2, continuing the same alternating sequence across the wall.
Mark the reverse of each prepared length in sequence so the alternating pattern positions are not mixed up when you move from the cutting area to the wall.
Establish a plumb or level guideline for the first strip so the pattern remains straight as you work across the wall.
Position each subsequent drop against the previous one and adjust it until the correct half-drop match is achieved, then smooth and trim as appropriate.
Before cutting a whole room: check the pattern repeat, match type and hanging instructions on the actual wallpaper. A half drop can use more material than a simple straight match, so quantity planning matters.

With a half drop design, careful cutting and numbering are just as important as the hanging itself because adjacent drops use alternating pattern positions.
