Polyester batting used to beard a lot. It no longer does especially if you make sure you are using a sharp needle of the correct size for your thread. I looked at the batting that you are thinking of getting. I am concerned about how light it is. It says that it is 3.8 oz per yard. The batting that I use is either 9 or 12 oz per yard and for most applications I use the 12 oz batt. The 9 oz batt can seem a little light at times.
