As in other reviews, some of the tiles were loose in the packaging.  There is not a mesh backing as listed in the description of the item.  So, we will have to tape the front together and then pull off the clear backing to be able to place the entire sheet on the wall and keep them spaced as they are on the sheet.  Had they been on a mesh sheet as described, it would be a lot easier.  Wayfair is notorious for having poor information in their descriptions as they never verify the information themselves.  Made in China - what do you expect?
