I can't stand it. It bugs me forever. However, others aren't in the least bothered by reverse fabric and put it in without further thought. Up to you.

I do this all the time. You pay for both sides. Why not use both sides?

WOW, you do learn something new everyday, I have never thought of using the reverse side of fabric.

On a quilting show I once heard the comment that there is the right side and the other right side, because whatever works best in what you are making is correct.

I tell my students "you pay for both sides, use the side you like the best".

You bet it have. I also repaired a quilt for my daughter's customer and found that she had used the reverse side of the main fabric to make it look aged. It was a beautiful quilt. Go with your 'gut' feeling.

It's fine to use the reverse side of the fabric to get an totally different effect. Go for it.

When making log cabin blocks, I often use the back side of the fabric. This adds variety to the fabrics I already am using in their similar shades. I consider it a bonus to have a fabric you can use either side of. :-D

When I buy fabrics, I am assuming that I am buying both sides. :-)

I recovered a chair years ago. I found some scraps recently and realized I had used the back side of the fabric.
