I work at a quilt shop and we just got in a bunch of Bali Pops and Tonga Treats. I was working on a shop sample and I think I was using the Tonga's... it's whichever one comes in the package with 2 strips next to each other, rather than the roll... whichever they were, they epically sucked. Width issues (though about half were slightly too wide) and they were cut so ridiculously crooked. Out of the 20 strips for the sample, I cut 10 with the strip folded on top of itself (the way we expect to cut, where you make 1 cut and get 2 pieces). I had to cut the other 10 one piece at a time x 7 pieces. Yuck
I had bought a pack of the 10" squares a few months ago and "square" is very relative. I would barely call them "quadrilaterals" (sorry, math teacher). After that, I swore all of those prepacks off.
