you can take it to my shop where you may get a bespoke of tailoring service. 173 york way camden london n7 9ln
otherwise here goes...
get a piece of material of very similar fabric. (enough to cover the hole area twice in area.
this is a very common problem by the way.
anyway when you've done that i would advice to over lock it(its a name given to a particular type of stitching) obviously sizing it so that it over laps(slightly) the damaged area concerned.
then stitch it with a similar colour to the fabric concerned. run the stitching over and over, going in a back and forth method. stretching the material as to avoid stitching over the crease. i would advice seriously doing this with machine and not by hand.
it may look vulgar up close but in the close proximity its not noticeable.
there is another way but thats best descriped in person and also depends on where exacly the damaged has occured.
