Bella style 8880 - 65% polyester/35% viscose 30 singles sheer 3.7 ounce jersey knit cropped tank top with loose boxy fit that hangs beautifully. If you dye it with fiber reactive dye, the viscose (rayon) will dye and the Polyester won't, so it will be very pastel. Or, you could dye it with combined iDye for cotton and iDye for Polyester, to get all the fibers dyed. Interesting and fun fabric to work with. Takes transfer papers or our new Transfer Inks beautifully because of the poly content!
