I wouldn't copy 3e necessarily. I see two disadvantages with it.
1. It provides too much detail. Unless you really need to know the difference between a +13 and a +14 to basketweaving, you shouldn't have a system that divides levels of basketweaving skill into increments that small. You probably just want to know, roughly, what a character can make.
2. It forces your ability to craft things to directly trade off with the skills that make you a better adventurer. Learning to weave baskets stops you from learning how to, say, ride a horse. This isn't good. Its better to have that sort of skill set off to the side so it doesn't trade off with combat or adventuring skills.
So... I'd just ask the players during character creation whether their characters have any background skills or knowledge, and then note it on the character sheet and handwave the details. For most campaigns, that should get the job done. Do you have specific needs for crafting?
