Consider visiting either a local Home Center or a Blind and Shade store. Both stores should haved PLENTY of extra instructions in the trash to give you. If they don’t, go ahead and white-lie them and say you bought them a while ago from the store and your husband threw EVERYTHING out by accident. At worst, they should be able to take a good set of blinds, open the box, and make a copy for you.
My best to ya and hope this helps.
