The great thing about printables for personal use is that you don't need to have a fancy printer or pay a printing company a fortune. Simply print graphics at home with an inkjet or color laser printer. You can find a printer for as little as $60 or upwards of $2000. Don't think you need an expensive printer to create incredible graphics. A printer in the $100 range should work fine.
Wording is important when you're writing a letter, especially if you're trying to carefully word a request. If you're looking for financial relief or forgiveness, I have new hardship letters and apology letters. If you simply want to thank someone, there are plenty of new thank you letters.
