If you don't own a Kantha throw yet, I think this blue one is a great choice. The patterns aren't too cluttered and look wonderful together. Plus, blue is a surprising and beautiful choice for color.
If incorporating patterns into your space is just too far from the norm, try and start with smaller accessories like these leaf-patterned fabric coasters. They'll certainly add a lot to any gathering, small or large.
The changing of the seasons is a great time to switch out bedding and other textiles. I love John Robshaw's collection of block-printed bedding. The colors are perfect for summer.
Prices range from $360 to $495.
John Robshaw quilts are my favorite. He always has the best patterns and they are so soft. I recently ordered this one for a client of mine, and I (not so secretly anymore) want it for myself!
Price varies by size, $325 to $425.
