First of all start with a piece of wrapping paper, pretty pages from magazines or a celtic carpet page. Paste 2 sheets together or back to back on card to make them nice and stiff.
Then draw a rough egg shape template, draw arround it on your page and cut out egg shapes.
Pearce a hole about 1cm from from the top of each shape and thread it with your chosen string.
From the garden or go for a walk and collect a small fallen branch or large twig and secure in vase, bottle or similar. Mine is secure in a cardboard postage tube.
Now hang your eggs on your tree with Christmas hooks. Use other eastery treats to hang aswell and perhaps even Christmas lights and voila you have an easter tree!
