Here is the Pineapple Trim Tool by Creative Grids. This is a great ruler for creating Pineapple blocks, fast and easy!

Create perfect 6″, 8″ or 10″ finished Pineapple blocks! By squaring up each round of strips as they are sewn. Since each round of strips is squared up before the next set is added, the blocks are perfectly square. The cutting requirements for the center square and the strips are printed right on the ruler.
The template slides easily over the fabric until pressure is applied. Then, our exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
The template comes with fully illustrated step by step instructions or scan the QR Code printed on the template to view a video demonstration.
