When attaching is paramount: patience, patience, and again patience. Make it work in the end but then definitely. However, one should the subject because of its size for processing in any case in some parts cut (eg, each line of text, and the two ornaments on the edge), to facilitate the work considerably. On the wall you need the blanks then only flush to install before you removed only at the end all support films. Especially to heed is that such films should not be as "normal" sticker peeled (and can), but be very careful and slow "peeled". Corresponding processing tips are however included. After a good hour of work (for couples), we were rewarded with a great element of style for the newly renovated rooms of our daughter (see our customer uploaded images).
One last point: whatever bothers us when the product photos to such wall decals, is the fact that the variables (eg in relation to furnishings) are often misrepresented (usually namely too large). For this reason, we have uploaded a pic of the finished result.
