Muslin Mates are used most for background fabrics, but can be used as other pieces in a block. They come in white, natural and muslin colors so are quite versatile.
The standard lines of Moda, depending on designer, do cost more because Moda charges more per yard to the shops.
These can run$9-11 /yard. Although I do not have any Modas in my shop that run $11/yard at this time. I'm sure it will just be a matter of time when I re-order that my cost will be more in 2011 than I paid in 2010. I will have to charge accordingly.
