I will lend most anything to most anyone. If it is valuable or expensive, it is insured and can be replaced if they damage or destroy it and then fail to replace it. Should someone 'borrow' and fail to return, they will not be the recipient of my generosity again. All my tools and machines are engraved with my name and books,etc have also been permanently marked for easy identification should anyone accidentally pack up something at the end of a class. I will very happily allow use of my things in my home, with supervision, training and clearly understood expectations for the safe and proper handling of the equipment or supplies. I have also gifted several people with machines, rulers and other supplies that I have duplicates of or no longer use. It gives me great pleasure to be generous when I am able.
