I am 76 years old and for the life of me I cannot understand why we have to have a special bag for baking potatoes. Was there a problem with the 'good old way'? Scrub the potato..Prick with a fork..Nuke for the required time. Voila!!! Baked potatoes. Same way with corn. You remember the old saying...if it ain't broke don't fix it. If you have extra time and material make a Linus quilt or chemo caps or lap quilt for a local nursing home. Thanks for letting me vent.
