This tile is already visible but the one on top of it hasn't been checked in... I thought this means that the quilt has reached its top row, but there is a tile already checked in into the row above this... What gives?

I dunno why my tile is visible, maybe because there is no tile above mine. Do all the quilts have to have squared tops?

is kinda distracting, but I like the bird shape.

I'm not sure, but having that bright a blue all the way around your tile kinda forces surrounding tiles to do scenes involving birds and planes and (ahem) flying saucers on fire. Especially when the BOTTOM of the tile is sky blue.
