On my modern brown couch/sofa I have five throw cushions and they all have covers made from fabulous vintage fabrics.
William Morris (1834-1896) was an influential English designer. I love fabrics and anything really with William Morris designs and William Morris style designs. I purchased the five cushion covers above from an online shop, William Morris Cushion Covers (link is at the end of the post). The second cushion cover from the left features a design by William Morris. The other four cushion covers are made from William Morris style fabrics.
Close-ups of the five cushion covers above from left to right:
"Bachelors Button" vintage linen fabric by Arthur Sanderson and Sons (original screenprint designed by William Morris).
A variety of fabulous vintage cushion covers can be found at William Morris Cushion Covers, and for a limited time cushion covers made from vintage Alice in Wonderland fabric by Charles Voysey are for sale. Here's the link:
