Get thyself to a craft store and get some suction cups that have little hooks attached. These work spiffily on glass doors! You could get several small ones to hang the lights, and a HUGH one to hang a wreath! Just make sure it's a silk one (which can also be purchased at said craft store) otherwise it may be too heavy for the suction cup holder.
Went to a movie and felt sorry for myself for about two minutes. Not being home is starting to get to me. I got a package of Christmas cds and some placemats today, and they said they're not putting up the tree until the wayward daughters (me and eldest younger sister) are home, which is sweet.
So this is my decoration! Also a bow on the door, placemats on the table, two candles, and the music. Not to rival Corin's, but it's my first year doing this on my own, you know! It looks really really cool from outside and nobody else in the complex has got lights yet.
