Parmesan and Feta Cheese making class of ~1.5 hours at River Valley cheese in Fall City. $65 with Groupon. Still too expensive. 
The hands-on part is only cutting the already made Feta and coating the already made Parmesan wheel in salt. Plastic gloves were provided to keep our hands clean. Total 16 students in this session (2 classes every weekend day). However, it's still fun. 
A cheese platter was laid out at the door (the fresh goat cheese with honey and lavender is yummy. The rest is not aged enough to develop a lot of flavor, and a bit on the salty side), which we could sample at anytime; a slice of cheese cake (made fresh today at 4am) was boxed for us to take home. As for studying material: a stainless steel bowl to cut the Feta, sea salt and olive oil to season it, and a plastic container to take home with. For Parmesan, we picked a wheel, rolled it in salt, and Julie wrapped it for us. A ~10 page printout with detailed instruction and link to resources. Only one student (it's her birthday) was called up to turned the milk while it congealed, and to scoop the curd into a perforated can to squeeze the whey out. Julie is fairly practical, teaching us to make cheese in a small home setting, telling us where to buy material and the reasonable price or how to go about making our own. Julie Steil, the owner, started cheese making 7 years ago (after a high rise management career). According to her, she was #6 in WA state at that time. Up to 2 years ago, she kept a herd of 200 cows + buffalo + yak + sheep + goat, breeding them and milking them. The cheese factory is just a garage. Instead of cars, it has a few deep sinks and fridges, a big tub.
Here are my notes + printout distributed by Julie:
After the class, swam in the nearby Snoqualmie River. A bit hard to walk on the pebbles with my injured ankles. Not a lot of shade. The water is very clear, can easily see where I was standing. The current is quite strong. I only stayed on the shallow side, which I could just sat on the pebbles with water up to my neck. Water was fairly chilly, especially the deeper running center. Refreshing for this hot afternoon (above ~80°?). Lots of people floating on brightly colored tubs fashioned with back rest and drink pockets. Often times 3-4 tied together. Saw one guy standing on a surf board and peddling down stream. A bit precarious. Relaxing and fun to watch them. Would be glad to return with some drinks on another hot day. Did tried Rattlesnake Lake. Even more people. Grass and shade, but water is a bit dirty. 
On the way back, dined at Sip Restaurant and Wine Bar, armed with 2 $50 gift cards (my birthday present that was nearly impossible to use without a car after their Seattle branch closed.). The cheapest wine flight ($15, I liked the first one, the lightest), an appetizer (good), 2 entrees (The short rib I ordered was way too dry. The tuna dish came with an interesting pasta, sweet and tangy.), 1 scoop of ice cream (not bad). Still need extra cash to cover the tip. Nice outdoor seating. Nice wash sink in the restroom. Almost empty in the main dining room.
