However, I could stand it no longer... They either needed to be replaced or repaired. With guests arriving tomorrow afternoon there was no time for replacing them.
Here you can see a few wear spots... but trust me the part that I replaced was MUCH, MUCH worse.
So.... I pulled out some fabric, made a few measurements and the viola!
I put a piece the exact size needed (the purple), pinned it in place and stitched it down. In about 1 hour of time they were good to go. Again! Now, I do realize that in time I will need to replace them, but for now, good enough.
