Phone #734-854-KNIT (5648)
-it's on Stearns Rd in Lambertville, MI (not far at all...follow Secor across the state line, left on Staerns, shop is on the right in the strip w/ Kroger; takes me 15 min from Sylvania Twp between Wildwood Metropark & the mall)
-most classes are knitting rather than crochet, but it's a great place so i thought i'd still give you the info. and/or you or your friend could at least call them as they would likely be aware of any other local resources/ classes for crocheting. (and/or a decent number of knitters who work at &/or frequent the shop have some crochet aptitude as well which they would likely be glad to pass on during open knitting nights, etc. for the very basics i would be someone who would be happy to help.)
the shop is a sort of "hang out" spot as well (for those working on knitting/ crochet - and sometimes beading - projects, that is). it's very welcoming with couches/ chairs available for anyone to settle down in anytime, a weekly scheduled open knitting night (though the same often happens other times as well), shop workers who are very knowledgeable & generally willing to help anytime, etc. all in all the kind of business i feel good supporting. and no, i don't work for them:)
- as someone who crocheted long before i knitted i'll put in a plug for knitting as well (which i realize is NOT at all what you asked for, so feel free to ignore). re: crocheting, i never took any classes (learned basics from a friend) but made a variety of flat/straight/square stuff (scarves, blankets, etc.) for years; my independent attempts at anything more, though few, were always met with frustration. and yet after only having started knitting in the fall i can already do loads more....not to mention that what i do is much nicer/ cleaner/ crisper (i.e. the edges). it wouldn't be an exaggeration to say that i'm a convert! (though am sure that i will still do come crocheting from time to time as well).
i only pursued learning to knit only b/c i'd "always" wanted to make socks & a little investigation revealed that socks are more suited to knitting vs. crochet. obviously i couldn't START with socks so i took the beginners class in the fall (met 3 or 4 times for 2hrs; the end result was a nice looking felted clutch purse) & am now taking the sock class (almost finished with my first sock!!)
hope this helps! and if you or your friend ever check it out & you run into a (generally) sunny almost-30yr-old in a wheelchair it's probably me:-)
cheers,

p.s. one other thought would be to check out the library. it wouldn't be an always thing there but i know a year or so ago i noticed they had a listing for a learn-to-knit class so it's a possibility...
