Here are a few less expensive small rugs and runners that I think would look really great stitched together. Pricing listed below.
Overstock Patterned Sisal: $194 for four rugs to make an 8x10. This rug looks a little more on the rusty side in person. I'd love to see it paired with this pretty turquoise twine!
IKEA Soften Rug: $150 for six rugs to make an 8x10. I think this would be a super dramatic and sophisticated look, with dark charcoal twine. I imagine it in a chic living room or a really cool office.
Pottery Barn Chindi Stripe : Make a 6x6' rug to go under a round pedestal table for your breakfast nook. $236 for six rugs. (I really want this one!)
IKEA Andrup Rug: $140 for four rugs to make an 8x10. What a steal for a GREAT play room rug! I'm loving that sky blue jute twine!
West Elm Izmir Dhurrie: $206 to make a 5x7 rug. I would pair it with this neon yellow twine for a super cool little boys room rug. It's outdoor material, so you can even hose it down! Keep some IKEA flokati throws handy for layered texture and comfort, though if you take a close look at all the images, the rug actually looks just like wool! I bet it's softer than most outdoor rugs.
I can't wait to try this idea out in our next place. It looks like such a simple over-under type stitch (blanket or whip stitch, maybe?). So very easy!
