These kinds of posts are why the flag exists. I use it liberally. Get to work gents.
I think your eyes are deceiving you. Those look like woven ties, not grenadines.
Those are good widths....Most of the ones they advertise as Gren. are very narrow. I ended up ordering mine from Kent Wang.
i'm no veteran by any means, but I think it truly depends on your local thrifts. if you can find out a general schedule of when they put out new stuff that may help determine when to go and how often to go.
there are some stores that stock so regularly that i go more often. others not so much. sometimes i'll hit the same store 3-4x a week but i'm sure it varies for everyone. in my area, i feel like some of the items are priced high, so sometimes i only go during the sale days, but thats just me.
