Try these:
It is a continuous layer of soft cotton which is placed between the top and bottom layer of quilts to give them bounce, thickness and warmth. Google the word "batting" to find out more. There are many thicknesses and sizes to buy. It is possible to also buy nylon and bamboo batting these days.
Well, that depends on what you are looking for in a wall hanging. If you want to do a medallion style wall hanging with an embroidered center block and then perhaps frames around the outside edge, then just find the design of your choice, stitch on the fabric of your choice, and then add a couple of borders in a slightly different color to make the design "pop". If you use a layer of cotton batting when you stitch it out, you don't need stabilizer,and it will give a little bit of cushion to your design. Good luck .
sounds good thank you. I will give it a try, however what is cotton batting.
