Take one ring shaped thing, in this case a polystyrene wreath, (it's not a polo mint, that was a joke, tee hee) and cover it with Christmassy fabric... I chose red, that's Christmassy!
start covering it with thin strips of fabric, also Christmassy colours... unless you want other colours..... (black and white ... humbugs!!!)
keep going until the hoop thing is full and trim the bits that are too long..... or don't and leave them long!
find one unfinished Christmas ornament from last year and attach it to the centre, he he he ... hang it on a door.... simples!!!
