For a higher pitch cut a little off. For a lower pitch add a small amount of plaster of paris a little at a time until you get the frequency you are looking for.
This is physics. There is a formula. Try a piano tunner.
take them out of the dryer as soon as the cycle stops or just a bit before. Use a good fabric softener too. Hang on hangers as you take them out and give them a good tug in all directions. That should work pretty well but won't look like they've been ironed. Some things just can't be replaced. Good Luck!
You could purchase a clothing steamer, they take way less time than ironing. It really depends on how wrinkled the item gets, I wear a lot of cotton don't have to iron anything because I fold it as soon as the dryer stops or hang them to dry.
Firstlybuy clothes that dont need ironing. Take clothes straight out of the dryer as soon as they are done and hang up. If something is wrinkled hang it in the bathroom while you have a shower. The steam makes the wrinkles drop out. If you really need something ironed and you dont have an iron. Put it flat under your mattress for a day or so.
