There are around 25 yds of the muslin on a bolt. That's more than we'll need but it is good to have on hand for backing other quilts. Plus it's all in the same dye lot which can be very important. Regular fabric has about 15 yds to a bolt. Prices vary place to place but mine is $2.99 a yard. Quilter's lament: 'You can always use it for something!'
