Although the product is available in a flat shape, perhaps a round shape would be even better for masks. I would guarantee that DIYers would prefer to use a round design as it could then be bent into any shape and inserted into the sewn slot so it would not move and no bead of glue would be required. This design allows the artist to insert the metal strip before sewing the ends of the mask. I myself use solid copper wire for this purpose, works like a charm, but aluminum is better for this. You can be the first to market! Masks will be relevant for many years!
