Bias Binding
 

I have to bind a 50 inch tree skirt. Because of it being round I am guessing I am going to have to cut my binding on the bias. I have 1/2 yard of the binding color. Will this be enough fabric to bind the outside edge plus the inside edge of the
tree skirt? I just can't wrap my head around figuring out the yardage when I have to cut on the bias. I was going to do the binding at 2 1/4". Thanks for any help or advice!

Do you mean that the diameter is 50"? If so it will be plenty, but for such a shallow curve I think you could get away with regular (non-bias) binding around the outside and on the way in/out of the center, and just use bias on the inside edge.

Here's a handy site to calculate how much you need. For a diameter of 50", your circumference is about 157, and you need another 50" to get in and out of the center, plus something around the center - say 15", depending on how big the center is. Add some fudge factor and you might need 230" or thereabouts. The chart says that your half yard will make 296", so you will have plenty.

wow that is some good math better than a calculator

Thank you so much dunster! I will make the regular binding then with the exception of the center circle. The site is great, I will be using that one often. Appreciate your help:)
