Crochet rugs and braided rugs use to adorn many homes when I was a child.
Everything was used or recycled and clothing was no different.
It wasn't a matter of being 'green' but a matter of money and very little of it.
Woolen Fabrics and cotton fabrics would be sorted by content, wool in one lot and cotton in another.
Women would save their left over cotton fabric for their quilt tops.
The wool often went into making natural rugs.
When rug yarn came along the rag rug was all but forgotten.
Crochet rugs were usually multi colored because they used what was on hand.
Women just didn’t go out and buy fabric for the purpose of making rugs.
Here are a couple of free crochet patterns I found. Maybe you would enjoy making them up and giving this old are a try. The old rag rugs gave warmth and color to the homes of the past.
We shall need quantities of carpet rags cut about one-half inch in width, the same as those used for making rag carpet.
Of course, you are aware that heavier materials should be cut in narrower strips than those of thinner materials.
You will also require a long, wooden crochet needle, about as thick as an ordinary wooden lead pencil, having a hook at one end, similar to a common bone crochet needle, only larger.
For a circular rug, crochet about twelve stitches (single crochet) over one end of a piece of candle wick or cable cord; or, lacking either of these, use a carpet rag of firm material; then draw the crocheted strip into as small a circle as possible, fasten and crochet round and round continuously until finished. The center of a circular or oblong rug may be a plain color, with border of colored light and dark rags, sewed together promiscuously, called ‘Hit and Miss.’
