Someone googled "will my eyes get bad if I do cross stitch" & ended up here. I'm not sure, but I think the answer to the question is no, not unless you do it in complete dark & why would you do that? What you might get is a hand that looks somewhat like this:
So, what do you do when extensive crafting has left you with a stupid looking hand that hurts & doesn't want to be your friend anymore? You make patches! Just make sure to ignore your doctors advice about no crafting for the next couple of weeks...
If you want to make your own patches you'll find the patterns on the new & improved DIY or die! page. Instead of a plain old boring wrist support thingy, you get one that might get people to think that you hurt your hand playing cool tunes on your guitar, or smashing the system with your bare fists.
Here is Skitystem (Sweden's finest) playing at the Obscene Extreme festival a couple of years ago. Since then they've split up, but just last Saturday they reunited to play a show in Gothenburg. Let's hope it wasn't a one hit wonder.
