I thought they would be simple. I just had to find the right size. But, there are many different kinds. I finally decided to take the felt and cotton batting pads from an old jacket. They're uneven, intentionally. One corner is longer than the other. By the time I'd noticed, I'd taken too much material out of the jacket to know which pad was which and whether the long side faces front or back.
I'm also disappointed in that I signed up for the Jo Ann's mailing list several weeks ago, and have yet to recieve a mailing.
