I got another fully transparent Sterilite bin today for only $16, very similar to Julie's:
Sterilite ClearView Latch 110 quart bin
Dimensions:
34 5/8" L x 18 3/4" W x 12 5/8" H
87.9cm L x 47.6cm W x 32.1cm H
(These are the greatest dimensions where the cover is attached, so the base is actually more like 77cm x 38cm at the very bottom)
I also got some green vinyl-coated mesh (1/2" squares, $12 for a 5-foot roll from Home Depot)--dark to see through it better, and small white plastic ties.
I cut a rectangular hole in the top of the bin and meshed it (still need to flatten out the mesh a bit). The end result is attached here. To demonstrate how transparent the bin is, I took a photo of it without flash--it's the more yellow picture (flash was reflecting off the bin, casting a blue tint on it, making it less transparent).
This bin is really big and cheap--highly recommended.
(Thanks, Julie, for the suggestion! <3)
