Ultra-flat blocks - Use the felt wool pressing bar to gently open seams on quilt blocks. Then place the bobbin base on it to keep seams flat while cooling, delivering the flattest blocks possible. Fabric protection and safe heat control - The hardwood base lets you set seams without fear of burns, even on cotton fabric. The weight of this press aid does the work for you, reducing the need for high heat and extra pressure. Efficient and comfortable pressing - The rounded part of the wool quilter clapper also serves as a handle. The inventive design provides comfort and ease of use, helping you be more productive and consistent when pressing quilt blocks. 2-3 practical use scenarios - After sewing a block, press seams open with the felt wool pressing bar, then set the seam and hold it flat by placing the bobbin base on top while it cools. - When working with cotton fabrics, use the hardwood base to set seams safely, avoiding burns while relying on the press aid’s weight to do the work. - Folding and assembling multiple quilt blocks, use the rounded handle for comfortable maneuvering and rapid, consistent pressing across large projects.
