1st of May except of International Workers' Day is also a spring holiday, that can be traced to ancient greek customs as they celebrated the officially begining of the spring. Making floral wreaths is one of the characteristics customs of May Day, and may also have its roots in ancient greek history.
This is my version of the wreath that I found at PerlillaPets blog, using this tutorial. It's a little bit different and is made out of plastic grocery bags.... hope you like it!
