This 100% premium wool mat is made in the USA. The mat fits perfectly on any standard sized TV tray. Easily press any pieced, embroidered or applique block. The density of the felted 100% wool mat absorbs seams and stitches, effectively pressing both side at once. It can also be used to block knitted projects by pinning them directly to the mat. Plus the texture of the wool stops fabric from shifting so there is no distortion from pressing.
