I tried out my red fabric for a quick check for bleeding and sure glad I did. Just a light pink in the sink, so I tossed it in the washer with a color catcher. Well the color catcher did its job and is hot pink. Lovely color but glad it is not on my finished quilt. Cutting blocks tomorrow! Yeah. Should I rewash this piece using Retayne? I am not generally a prewasher so I am new at these products.
