Here's what it looks like: I have to join the single thickness with the double thickness of foamcore. How ? The only idea I tried: sparkling compound. The result is okay but the grade is WAY too steep ! I tried many times to soften it but sparkling compound is not easy to work with ... I cannot lay it in small amounts, it just wont stick... I need help ! Any suggestions ? I don't have to tools to make a grade out of wood ... foamcore and foamboard have been tried but I couldn't get anything out of them ... any suggestions for a guy with two left hands ? (and probably two left foot) And now the goodies ! Here are two shots of the soon-to-be main street ! The beige building is the cinema: Thanks a lot !!!
