Great work and thanks for sharing.
It was just the motivation/idea I needed. Actually thought several times about doing the a vintage style gas pump for the garage, but don't want to lose any floor space. So, changed course and considered one of the old Gulf Oil signs (there used to be one near my house growing up, always like the style and color). Looking around only found small 12" sized ones and the large (usually original) were more than I wanted to put into it. Hadn't thought about doing one from foam.
I got started on it this weekend. Was able to get everything cut out on and shaped on Saturday & Sunday, painted & assembled yesterday, and finally cleared it today. Very happy with it, around 4' diameter, easy to hang (when I get around to it), and only about $15 when all said and done.
So your post helped introduce me to a medium I haven’t worked much with in the past, but can see plenty of uses for.
