Remember flannel shrinks quiet a bit. You may want to wash and dry it in the dryer befor cutting it out to prevent any supprises the frst time it's washed. Nothing worse than a new flannel blankie with a satin binding that shrinks the first time it's washed and them the binding is way to big and just gets all wavy and will not lay flat. Since flannel will soften up after washing, you can use spray starch when you iron to make cutting and piecing easier.
