The only time I had trouble with glasses & such being tipsy was years & years ago I used a higher loft polyester batting. Nothing sat evenly on it. Just too bumpy with the high loft & quite heavy quilting. That was the batting I had on hand but I never used it again for table toppers or placemats. These days I always use cotton batting or 80/20. I also have used fusible fleece but I always have batting on hand so use that mostly. Have fun!
