I like KarensRopeWorks and these Cotton Nautical Doorstops which are monkey fist knots (from huge monkeys!) More mats, boat accessories, and rope work in her shop.
More knotty art Big Sailor's Knot Necklace made by Cristina Olariu an Architect and knot artist. Check out her shop elfinadesign for more great work.
The featured item in this catchy collection is this navy blue turks head knot sailor rope bracelet made from hand dyed cotton cord. There are more designs and colors available in WhatKnotShop on Etsy and if you don't find something you like there visit WhatKnotShop on Zibbet for an even bigger collection.
