I was wondering if any of you have machine quilted on tricot. I have a quilt that my great grandmother made that has tricot on both sides, that I love. I would like to do one for my granddaughter that is due in June, but I would like the bottom to be flannel. What type of thread would you use (cotton might be too heavy) and what size needle. I know the needle needs to go through the flannel, but I don't want the holes to be too big on the top.
