Not sure I saved photos as I dumped most of my slides (know even having such things dates me). But I remember two projects.
One was for a little girl's room that was supposed to be princess like. The interior designer (and parent clients) wanted something less formal and less expensive than picture frame moldings (figured she would grow out of the look in a year or two) for her posters and things. I taped off "stripes" like you would if painting them and took the girlfriend du jour's pastry bag and cake tip set and experimented until I got kind of a cool looking border. Then I duct taped the tip to a caulking gun so I didn't have to keep filling little bags. The mixed caulking was a little soft but it worked out well. Your trick of filling compound into one would work better I suspect.
I let it harden. Primed and painted and then burnished in some gold leaf here and there.
The other was providing a series of "buttons" or "exposed" tack heads for a faux finisher doing some sort of simulated tufted paneling for a bar or reestaurant. I just snapped chalk lines left/right and up/down and used a cake tip in the intersections. I did use a pastry bag and hot mix for this as the tube stuff was too soft to give a crisp edge. I was swamped at the time and moved on to other projects. I do not know how that project turned out but the person was one of the best at faux painting (I just do not have the patience and think much of it looks out of context and looks stupid!).
The other project I mentioned, not mine, was the dome of the State Capital in Sacramento, California. Most other contractors bidding the restoration insisted molds would have to be made of the broken moldings and recast in plaster or whatever. In some cases this was true but the thing is 200 something feet in the air. My friend said he could fix most in mid-air to the point nobody would notice and cake decorator tools were the way he pulled it off. I think he ended up making some of his own tips but no biggy. It is just tubing. Whether he made any money I don't know but he got lots of publicity. And we were both emerging art students. I had just grown up around painters---not the fine arts kind---so had trade skills.
Have fun! Thanks for inspiring the memory.
