Worked on window trim today. Here is how I'm doing my trim. Glue the bottom trim piece onto paper into the horizontal corner of a small Square. Then glue the side trim piece against the vertical side of the Square. Finish gluing the other side and top trim piece in place. I find that the square helps keep everything lined up nicely.
I'm a maker and a thinker. I live in a magical world inside my head. To some, I am an artist. I am surely creative. And my creations change as quickly as my mood - so you never know what you're going to get.
