I tell anyone that will listen, to buy good quality, or Quilt shop quality fabric. Here is a perfect and disappointing example of what I mean! Both these quilts belong to my mom. It would be so nice to preserve these lovely quilts for a very long time. The one on the left is only a couple of years old. It was pre-washed, pieced, quilted, then laundered once. It has not been used or exposed to light. Note how yellow it looks compared to the one on the right! It is so sad that all this effort has been spent and know, the fabric is not holding its own. For me, making a quilt is very special and labor intense. I imagine if you quilt, you do it for many of the same reasons. I do not know the mfgs of these fabrics, since selvage is long gone. I do not she is on a fixed income, so she uses lesser expensive fabrics, purchased at JoAnne's or Hancock Fabrics, (not to be confused with Hancock's of Paducah).
I am not saying lesser fabrics are all bad, I am simply saying, consider what you will do with the fabric and how invested you want to be. The particular choice in the white fabrics for these 2 projects will not likely stand the test of time, at least the brilliance of the white fabric.
I hope this post will help someone 'GET' what I have been trying to say! 'You get what you pay for'!
