I did the first two pairs, washing and wearing for a week, and zero problems.
The polyester batting even felts naturally when wearing.
Similar to picking up dog fur from the floor and having it felt with the socks when wearing, without the pilling stays flat, so far.
I have some jeans I’m thinking about repairing that way. I just don’t want to rip a seam to get to the below-the-knee hole.
I can see it surviving a cold water wash, but the dryer would shrink wool. Maybe if I needle on some polyfil and surface design with a synthetic fiber... I have some cellulose.....it could work.....
A piece of thick foam would give a firmer patch than a brush, tho. I use a brush only for thin, delicate forms, like ears.
Now, if one of my larger, sturdier needles could handle the denim....
It may be a while (other projects), but I’ll report back if I get to it, either way.
Thanx for the post. You always come up with great solutions!
