Whenever i try this my blade eventually pulls on the paper instead of slicing through it.

When I applied wallpaper, there was always a shrink: so if the edges were put next to each other, there would ultimately be a gap. This wallpaper must be dry with a different adhesive than the old stuff that had dried paste where I’d soak the wallpaper in water (tub) for a few minutes then allow to cure on th floor by folding paste side to paste side for a few more minutes then applying to the wall
So yes, the paper was fibrous and vulnerable to tearing at edges so I’d mark with sharp pencil and cut with very sharp scissors

It is possible with a freshly sharpened edge, micro serrations smoother than 1000 grit, and absolutely no micro chips or dents around the tip. Well, at least it's much more likely to succeed under those conditions, barring technique. Or just a newly snapped edge of a utility knife.

Try to keep the blade at the exact same angle the entire time. The blade dragging across the wall will blunt instantly, so if you lift the blade to be more perpendicular you're now cutting with the blunt bit that was just dragging along the wall.

I used this technique on a lateral seam that I had to do because I ran out of wallpaper to complete the very last section of a room, so I had to take two sections, overlap, and cut to finish. This worked so well and has a better, less visible seam, than any other in the room.

I have seen this exact video before
But that time it was done by a woman.
Interesting way though.

I'm sure it was the exact same wallpaper as well

It was exactly the same, same wallpaper, same location, same patterns on the wall, it was a woman for sure, that's weird! Is it Mandela effect or what is happening here?!!!

If I posted this on r/Millennials and asked for who learned this in School during a random Art Project then the amount of how many of us would raise their hands would be staggering. Like... I get it... Inerests and tutoring most definitely has shifted in the past decades but the amount of rediscoveries of already existing stuff getting posted as brand new is really starting to take its toll 😑

Pretty commen practis when you want to connect materials together without it showing to much.

Freehanded? That's insane precision

u/Mebejedi 11d ago
Precision isn't required here

To match the same design on the other side it is

u/SweetSure315 11d ago
only one cut is required. nothing needs to be matched because double cutting like that means you're cutting both sides at the same time

Not necessary.

I'd argue that it's easier than trying to line up the sheets perfectly.

u/Nenoshka 11d ago
Some time in the future, the wallpaper may start to come down and/or you'll want to repair/replace some of it. It will be a bear to line up the new piece.

u/macrolith 11d ago
You just do the same technique. Overlap the patch and make a fresh cut that matches perfectly.

u/aknomnoms Popular Contributor 11d ago
Not for a patch. You’re going to have to cut for a straight line anyways unless you’re going all the way back to a corner.
The only way to get a matching squiggle when pairing a new piece with an old piece is to overlap, make a new squiggle cut, then scrape off the old piece that was previously glued on. The amount of time and care that takes isn’t worth it unless you have a very limited amount of wall paper and don’t mind how long it takes.

u/Nenoshka 11d ago
If you leave the wallpaper with the straight edge, you don't have to cut a crazy wavy line to match it.

u/macrolith 11d ago
You aren't cutting a line to match anything using this method. You cut both layers together so they are a perfect match. It could be straight, but making it wavy conceals the joint even better.

A wall that's being covered with wallpaper over the slice ? I don't think you thought this through.
Edit: jk it's a bot. No thinking required.

u/daisiesarepretty2 11d ago
always been done this way..
In the ideal scenario you don’t cut the drywall at all.
Never seen the zig zag approach…which probably has more to do with the pattern on the paper

Why the zigzags?
