So, I bought some white ones at the thrift store and sewed a decorative fabric border on each. They look really cute and I am satisfied with the results. Sometimes you have to take matters into your own hands and be creative.
Many years ago I decided to make a quilt. I precut squares in four different fabrics: navy blue, blue small print, white and sky blue. Having had no experience, I laid out the pieces on the bed in the pattern I liked and began sewing blocks together and then rows. It took hours, but it did look pretty. Then I discovered my major mistake. I had used cotton material on all of the squares except the sky blue ones. They were polyester. They stretched and would not hold their shape. It was a learning experience.
