The writing is "Goblin Guts" glowin the dark spray stuff I get from HEB usually pick up 4-5 cans after holloween when it's on sale. The nice thing is that on a light colered brick like we have you can barely see it durring the day. Infact when I set up the Blacklight this year I found out that I had only washed off about 1/3 of last years so all i had to do was touchup.
The spider web is fishing line - I have a Photon UV coin cell flash light that I used to find the strongest flourescing line I could. The pics really don't do it justice. It was getting washed out by everything else.
