If you do not have an old bedsheet or wood dowels/garden stakes on hand, we've compiled some good sources of eco-friendly materials:
All three of these fabric vendors provide friendly and accessible customer service and are happy to help recommend an appropriate fabric for your project:
• Pickering International offers several eco-friendly fabrics including organic cotton, linen, hemp, bamboo and soybean. Swatches are available and they also sell remnants.
• Furnature supplies certified organic cotton in a variety of colors and weaves. Remnants available.
• Green Sage sells organic cotton, linen, hemp and flax in a wide range of colors, weaves and blends with a minimum purchase of only one yard.
Be sure to look for wood bearing the Forest Stewardship Council (FSC) label; many Home Depot stores offer several sizes. Bamboo gardening stakes in a variety of lengths are sold at gardeners.com.
Presto! A little modesty at a modest price.
