I have 2 trees that I need help estimating on how many mini lights I will need. I buy them in 25' strands. Both trees are oak trees, and I will just be going up to where they begin to branch. 1) 10' tall & 1' in diameter. 2) 10' tall & 1.5' in diameter. Can anyone help me estimate how many strands I will need? I will be using village lights if that helps any. Thanks.
