Make a mold (cardboard and sellotape worked great) I covered mine in Tinfoil. Cover some rope in glue any project glue will work and stuff it into your mold press down a little and leave to dry - when dry take out of mold and put a piece of ribbon through to hang it up with. Here is a picture of my mold.
Next is the polystyrene egg I covered mine in some beautiful tissue paper that I got from the grocery store. Simply cover the egg with glue and then mold the paper around. I tied a ribbon to each one so I can tie it to my wreath.
Then the fun recycling bit - I took a cereal box and cut a long continuous string (as you would make a snake out of a sheet of paper) from it. Mine is about .5 cm thick and as much as I could get out of one box this I then tied to an old wire coat hanger that I pulled into a round shape.
Have a Crafty week.
