Fold each doily in half, then half, then half again so when unfolded, your doily has eight folded sections.
Refold the doily in half and at the center point fold, punch a small hole half-way through the fold. Thread a plastic needle with yarn and thread the doilies on.
To keep them from sliding, tie a small piece of yarn between each doily. The beauty is, you can slide this piece up and down the yarn to adjust the look of the garland. The closer the doilies are to each other, the fuller and better your garland will be.
Hang up your garland and wait for the 'ohs' and 'ahs'
