I'm thinking of doing a smaller scene for my haunt this year as my son is getting married Oct. 23 (not halloween themed btw, who's son is he?). I enter a yard decorating contest and am defending my 2 year in a row championship. So I'm doing a graveyard theme in my front yard and thought a tunnel of some sort along my sidewalk would be cool, different and spooky. So... any tips on doing this in a budget friendly way, perhaps using small trees as the "walls" with some sort of support underneath? No big bash for Halloween for me sadly however my sisters and I are driving to Salem Mass. for Halloween and donning our Sanderson Sisters costumes. Can't wait! Thanks for any help!
