I want some but have never done it before and I'm not sure what to do! 
What are yours attached to?
We have no guttering (bay windows at front), no tree or hedge to drape them over.
What are they plugged in to?
I don't have any outdoor sockets. Could I out the cable through the window, shut the window and then plug them in inside?
Where did you buy nice ones this year?
TIA! :)
