I used this to get to 55 clothcraft, I got skill ups a lot quicker than with green ribbons very noticably. On Odin server silk cloth stacks have clibed to 150K when they were 70K several months ago -_- linen isnt quite as bad on our server at least you should check if you'd do better with this. craft on ^_^
Edit: Just a by the way~ When you start getting closer to cap its better to switch to green ribbons dont ride this to the cap because it starts becoming more gil per skill up. This is just my opinion, you can do whatever you want but hopefully this will make it faster for you. ^^
Cheaper to do then green ribbons (on fenrir that is) and sells back to guild for 3.5k if i remember. Much better then the 2k you get for the green ribbons.
I'm gonna try it, save it for GP, simply because I crafted a whole stack of green ribbons at 53 for a whopping .1 skill up. they may not sell well, but they are a lot cheaper to make, and better skill ups for the lvl (at least on midgardsormr) than the green ribbon.
--edit
after trying it for a while, linen cloth is expensive, and I have gotten a couple skill ups, but I'm not entirely sure it's the best item to skill up on.
