I only used kona once and it frays way to much for me, but on the upside it does have a nice weight and feel. I prefer a heavy muslin(Legacy) or a white on white print.

I use both muslin and regular white cotton fabric - like everyone else depends on the project - if its an antique-y looking quilt I will use muslin - otherwise I love good old white for borders, sashing - it looks very clean and crisp.

where is Kona muslin made?? i noticed Legacy muslin is made in China.
ah, found it. Pakistan!

Yes, this is what I use too when I use white. When I use a color, I use Kona or Quilter's cotton

I really love the bamboo/cotton muslin I bought in Joann's last year. Enough so that I went and bought a second bolt.

Otherwise, I use high quality white sheets- thread count about 250. I know that many don't like to use sheets, but I buy sheets and sheet sets in Ross or TJMaxx and don't care if they are irregular. The first thing I do is rip off the elastic on the fitted, and tear it into rectangles more easily used.

I often use the fitted sheet (of any color) as the sashing in a quilt, then I use the flat sheet for a backing, and give the quilt with the pillowcases, which match exactly.

Thank you all for your wonderful insight!

BRILLIANT!

Usually muslin. Sometimes a white on white if it really sings to me.

I like white on white. If the print is too glaring I use the wrong side of the fabric.

I love white on whites, but I have such trouble telling the front side from the back side, that I have almost given up on them!
