Day/night shade question...

I went nuts restringing our large side window day/night shade. Work on a king size bed. Follow restringing diagrams and instructions exactly. Look carefully at how stuff goes before taking apart. Four string (large) shades are more complicated. I bought restringing kit at Camping World. Use ingenuity and masking tape, etc. to hold sections together while you work. Be careful not to rip sections. If needed,use crazy glue. Take a break if you start tearing your hair or sweating a lot. I used thin stiff wire with eye bent in the end to grip string to thread new string through sections but there are long needles available.Leave enough surplus string for bottom ends. Side strings must be tight when finshed. There may be a service locally who will do this for you. Some RV'ers replace day/night shades with other types.
