Tensisters 1 inch Finished Grid Panel

The grid lines are crisp enough to see through without a lightbox, which made my half-square triangles align perfectly. I love that the 1.5-inch unfinished squares match my usual cutting size, so there's zero math involved. This is going to be a permanent fixture on my cutting table.

This panel saved me so much time squaring up my half-square triangles. The 1.5-inch unfinished squares make it incredibly easy to chain piece accurately without any guesswork.

The grid lines are crisp and dark enough to see clearly through fabric, which makes lining up the 14 blocks across a breeze. I’ve used it for three projects already and it still lies flat without any curling at the edges.
