Jean :
I found out you should have your machine professionally cleaned and maintained after you sew on flannel. My feed dogs were packed with lint, and my machine guy put all the lint in a baggie so I could see the large amount. Also, I sew every day, and they suggested I bring in my machine every 3 months for cleaning. (it's free)
I made pinwheels. I ironed some with all the seams opened and some with just the last seam open. It only made a difference in the points in the middle.
I made the mistake of the last border being on the bias -- it was a pieced border -- and the machine quilter asked me to stay stitch the edges.
One book said to bind with regular cotton, but I bound with flannel and it wasn't too bulky.
Have fun!
