Nymo thread is an especially strong thread used for beading.  Nymo was created for the shoe industry to attach the bottom of the shoe to the top of the shoe. The sizing is somewhat peculiar, ranging from the thinnest "OO'' and "O" to  "B", "D", through the thickest "F".  We carry B and  D which are good for necklaces and bracelets.  For bead stringing, you might still double-up the D thread for any piece.

We sell Nymo on small bobbins.

Size D is most widely used.
