Hello again. Thanks to all who have replied to my original message. I really admire everyones work here, it is inspiring. I chose to use the GEII only because of immediate availability. I will order MAC when I am ready to do more. Now my question is- Since this is a silicone base will the pieces have movement at the joints? One piece I did has a lot of movement,even after cure time, where 2 pieces join. I am worried it will come apart when I place it in the garden, especially if it leans at an angle. It is also my best piece. Any suggestions or advice? Thanks again
