To get to Cedar Hills Joann's: Max to Beaverton Central (the stop which is not Beaverton TC) and then follow these FABULOUS WALKING DIRECTIONS:
That's right, the best way to walk from Beaverton Central to Cedar Hills is to cross some empty lots full of construction crap. If that seems dangerous, (it's really not) just follow the Max tracks till you hit Cedar Hills Blvd. Then you walk up Cedar Hills for a decent length of time. Eventually you will reach Walker Rd. What you'll actually see is Five Guys Burgers & Fries, which is on the corner of Cedar Hills and Walker. Turn right on Walker and you'll see the tiny Joann's. It isn't super super small, but it has less of the craft stuff and is mostly actually sewing stuff. I think there's less of the quilting and sports-team oriented type fabrics.
To get to Tigard Joann's, either take the Wes or the 78 or 76 to Tigard TC. From Tigard TC, Google has legit walking directions.
That area might still be under construction, though, so it'll be awkward to walk in like last time.
Yagi: ... I did put it in the pantry, didn't I? XD
Well, you're welcome to the Larabars and the undoubtedly gross lunch container.
