The 13.5" x 13.5" and 17" x 24" wool ironing pad bundle is a great addition to your quilting kit – whether you are a beginner or an expert! Our pads are made from 100% Authentic New Zealand Wool, which has dense fibers allowing for excellent heat retention. This provides heat from both directions while ironing, making the pressing experience quick, easy, and efficient. Say hello to crisp, flat edges in no time! Additionally, the wool fiber texture helps grip patches and avoid slipping while you are pressing. It is a great surface for pinning and blocking fabric. The pads are versatile for various projects, including embroidery or sewing projects! Each pad is ½ inch thick, which protects any surface from heat damage. Our 17" x 24" inch mat, is the perfect size for standard and large quilt blocks. While the 13.5" x 13.5" is perfect for smaller blocks and piecing. Our compact mat is easy to take anywhere – to classes, guilds, or just around your home! Use & Care STORAGE - The pads are made from dense fibers which will lose their integrity if they are stretched – please store flat and do not roll. CARE - Our mats can be easily hand-washed and left to air dry. We do not recommend using a washing machine as this may damage the wool fibers. STEAM - Our pads are made for ironing and use with heat and steam. Please be aware that as our product is made from 100% authentic wool, the use of excessive heat and steam may result in a temporary aroma. STARCH - When using starch please be cautious as it may result in a residue build-up on your iron. Excessive use of starch may cause discoloration of the mat. For more information go to our website.
