I have a quilt top done and want to make it super warm as the hubby gets very cold, but not super expensive. I already have a Hobbs polydown coming from Connecting Threads, but am wondering about adding a second batting. Is there a batting that will play well with polydown, but still be warm? I am going to be fmq on my 6600, so can't make it overly thick and heavy. The backing will be flannel. I kinda feel like I am a rock in a hard place. Any suggestions?
