It´s called simple pineapple block. Theresa DownUnder shows you how simple it really is!
Pineapple Block
Jenny demonstrates how to make an easy Pineapple Quilt using the Creative Grids Pineapple Trim Tool, 5 inch squares of precut fabric (charms) and 1.5 inch strips of precut fabric (honey buns or skinny strips).
Create perfect 6"; 8"; or 10" finished Pineapple blocks by squaring up each round of strips as you go. Since each round of strips is squared up before the next set is added, the blocks are perfectly square.
