Personally, I swore off wallpapering a long time ago. Having purchased a century home, the two previous occupants of which had both been septuagenarian, for hours on end my husband and I steamed and scraped off dated patterns in ridiculous colours.
Then, as wallpaper was still all the rage and we had plaster problems to hide, we reapplied new designs, matching seams and corners on walls that had never been straight. Only, of course, to remove them a decade or so later when paper became passé
Never, never again would I use wallpaper I swore then and never, never again have I.
Which, of course, takes nothing away from its versatility. All the attributes it had then it has now.
The same can be said of using seamless wallpaper or repeating patterns in graphic design. There are so many ways to use them in projects whether you're a scrapbooker or a professional designer. What's even better is that if you have image editing software you can create your own motif taking expertise and imagination to the next level.
