Invisible mending was a common practice until the 70s. But with the advent of the 21st century, it has become a fine craft related with tapestry weaving. Apparently, mending in general is included in industrial methods of carpet restoration, but speaking otherwise, invisible mending in Perth is a delicate service, offered by skilled carpet workers.
Basically, it is a process of weaving that consists of rebuilding the fabric of the carpet. Lots of threads are taken from another part of the carpet which is hidden by the side of the burned or cut portion. These removed threads are woven back into the damaged area to match it with the original strands of that particular area. Once the restoration work is complete, it becomes virtually impossible to detect the mended part on the outside of the fabric even with careful observation. The only possible way to find out an invisible mending is to turn over the carpet and look for the long hanging threads where weaving was actually done. These threads are visible because invisible mending is done without tacking.
Although all companies that provide carpet repairs in Perth do not offer invisible mending nowadays but if you do some research work you will surely find someone who still offers this kind of job to their clients. When you are looking for a company that provides carpet repairs, specially for invisible mending, always be careful enough so as to contact one with experienced workers and a good reputation among customers. Since invisible mending requires a lot of precision, only a putative company can offer you the best service. The carpet repairers working in such companies are more familiar with the fundamentals and well-versed with the improved techniques.
