The kids have noticed that Uncle Norm's old quilt is quite threadbare and they decide to make a new one using a super cool design. With help from the Inventonator, they see that interesting designs can start with just one triangle! The Rads pay a visit to a star quilter, who teaches them how flipping, sliding and turning one triangle can make some really awesome patterns!
