Perle CottonsAll of our pearl (perle) cottons are 100% hand over-dyed cotton, with #3 being the thickest and #12 being the finest of the four weights. Each of these fibers is perfect for needlepoint - as well as a variety of other techniques, including blackwork, huck embroidery, tatting, quilt knotting and more - and can be used on different mesh canvases.
