the first time I made one of these Christmas wreaths was years ago. I used red and green Christmas fabric. I decided I would make one for this Christmas, I had lots of satin and voile type fabrics that I have had for a long time.
First I bought a 16" polystyrene wreath base, then cut up small squares of fabric. These dont have to be exact or the same size. I use a knitting needle to poke the centre of the square into the polystyrene and keep going until the wreath is completely covered except for the back which isn't seen.
