Estimating Rag Weft Material

Weight wise, you can figure it will take about 3 to 4 pounds of rags for a rug. Which is roughly about 5 oz. per square foot.
To find strip width, it would be best to cut a few strips of different widths. Weave a few rows with each and decide which one you want to use.
Generally, for material such as sheets, strip width will be about 1-1/2" to 2" wide. The thinner or more worn the material, the wider the strip. Thick material, such as jeans/denim, will probably be more like 1/2" to 3/4" wide.
A starting formula you can use to help determine the amount of yardage needed to cut strips for a rug is as follows:
W x PPI x L = Y
Y divided by 36 = # of yards of fabric needed
W = the width of the rug on the loom
PPI = the number of Pick per inch you want - if your strips are very narrow - say 1/2" or less you will have more ppi than if your strips are heavy, say 1" or more (You will need to do some samples to see what your ppi will be)
L = the Length you wish your rug to be
So for an example let us use your 3 x 5 foot rug. Let us assume you will be using Maysville cotton rug warp sett at 12 epi and strips of 3/4" material that allow 6 picks per inch.
Your formula would be:
3 x 6 x 5 = 324
324/36 = 9
So you could plan approx 9 yards of fabric (let us assume 45" wide) were needed to do a 3 x 5 foot rug.
I have found this formula pretty accurate, but of course one must take into account beat, sett, etc, so plan a little extra so you don't run out.
