Holy MOLA!! ( I can't believe I am the FIRST to say that here!! lol !) I bought several while we were in Panama a few years ago. The Kuna Indian ladies use ANY material they can find. One of mine has cotton, poly, a poly blend, gingham and some other fabrics I can't define. Most were made the traditional way by hand stitching and one is done on sewing machine. I just love them.. A guild gal is gonna teach a class on making MOLAS. Hopefully she will wait for me to quit SNOW-BIRDING and teach the end of April..... keeping my fingers crossed as I REALLY want to learn this technique. I framed mine! You are one lucky lady to have all those beauties........
