Best Answer - Chosen by AskerYes, there is two possibilty for you :1) Use a Crafters Hot Glue gun and Glue Stick be sure use a Ext. cord and A -Frame Ladder also.a) put small amount of Glue in the mortar joints, then either use and old style cup hook into glue. then install the Wreath. If you are not able to use the cup hook. Then plastic or other metal hook object for hanging pictures or big objects.2) The other way is at some of the Ace or True Hardware , orHome Depot,Lowes outlets stores. They should have in their seasonal Christmas items, small metal brackets ,that will wedgeinto the mortar joints. These metal brackets also have small hooks that will allow you to install the Wreath also with wire.Yes, You should not have to use a drill for this either.However My Best working thing should be the Crafters Hot Glue Gun. ***Most Bigger Commerical Installations for Seasonal Lights use the Process of the Glue Gun for Best results and less Damage when installations ocurr.*
