I have found it easier to use one piece of wire for every two strings. Done properly  the strings will break much less often than individual strings with one end twisted.

Slide one end of the wire into the harp and out the next hole

Make sure the wire inside the harp is loose and round.

At this point you do NOT want any bends or kinks or corners.  Once the wire bends tight to the corners like the lower one above the wire cannot slide from one side to the other.  This only works with wire strings. Nylon or gut IS flexible enough to slide around corners, brass wire won't.
Cut the wire about 2 1/2 inches past both zither pins. I use my four fingers to measure the two ends together.
Or you can put one end through a zither pin and  then pull the other end tight and then cut.

I like to bend the end of the wire into a loop so you can't poke you fingertips.  Then pull the wire back through the hole and wrap it around the zither pin 3 times  counter-clockwise, twice inside (between the hole and the wood) and once to the outside.. see photo.


NOW to the same with the other string. They should look like this BEFORE you start turning the pins to tighten.  

Turn the Zither pins CLOCKWISE in TINY increments; first one then the other, until both sides of the wire are just barely tight enough to sing. DO NOT try to bring them up to pitch  at this time, but you can tune them a half-step lower. Tune the C strings to B, the G strings to #F, etc.
The inside wire will look like this after the strings are tight.

Once all the strings are on, make sure they are all in a nice flat line with each other. Loosen some and bring the final wrap in or out to match the rest.
 This will be very important once you start playing and even more so once you start to play quickly.
NOW take the Paint Pens or markers or nail polish and color the C strings Red and the F strings Blue.

Begin bringing the strings up to pitch starting with the longest, thickest string and working up.

Brass Wire strings DON'T STRETCH, so use TINY little tweaks.
Do not tune any of the strings sharp.  After the harp has been tuned for a few DAYS you can try tuning to another key using sharps. But not now. If you want to tune to a key using Flats, that would be OK.

 Start with the key of C. These Harps are designed to be tuned to C. It's very important NOT TO OVER TIGHTEN  any strings until they've had a while to "settle" .
You will also notice a slight bowing on the soundboard as the center of the soundboard "bellies out" about a quart of an inch.  THIS IS NORMAL.  If ypu ever see a harp that does NOT belly out a little, there's something very strange, or something very wrong about that harp.

I could use some feedback as to how easy this is to understand.
