To put bead garland on a Christmas tree, follow these simple steps: 1) Begin at the bottom of the tree and work your way up, spacing the beads evenly as you go. 2) Beads can be threaded onto the garland using a needle and thread, or by wrapping the end of the garland around the bead. 3) To avoid tangling the beads, use a gentle hand and try not to twist or pull too hard. 4) When you reach the top of the tree, secure the garland with a knot or tie. Have fun decorating!
