Attaching and rigging the yards to the masts are pretty straight forward in all of the kits I have encountered. There two important points to be noted here: 1-keep the yards as as even to the deck as possible. Do this by rigging one side of the yard and hold the rigging down using clamping tweezers or anything sufficient to hold the yard in place without knotting. Then rig the other side, pulling until tight with the yard remaining even, then secure with knots. Go back to the first side and secure with knots. 2-Always try to keep the rigging line as tight as possible. Loose lines do not look so good!
