An Idea for full face masks that won't stay sealed

Try a 1 or 2 inch ace bandage wrapped around the mask and your head, or go to your local fabrics store and get some velcro and a piece of comfortable material. Put your mask on. Take two pieces of 2" duct tape, about 6-8" long and put them somewhere on either side of the mask. Pull the ends of the duct tape towards the back of your head as if you were going to fasten them together. See if that helps seal the mask better. If not, try a different place on the mask, and repeat the process. Once you have determined the best location for the duct tape, glue or use double-stick tape to adhere a couple of the velcro patches to the mask. Then cut out a piece of material to basically make your own head gear, and attach glue or sew the other velcro patches to the ends of the head gear, and attach them to the mask. Remember that your supplemental head gear will stay in place better on the back of your head if it is 3-5" wide at that point, tapering as it gets closer to the mask. Now, please let me know if this works, as I haven't even tried it yet. The idea just came to me when I read about people having air leaks, as I do myself. Well, off to the fabric store. Also, who do I know that can sew...???
