@mathiasx I have not… always made my own stencils either by laser cutter or vinyl cutter or 3D printer.

@rasterweb @mathiasx seems like lace would be hard without some sort of jig keeping it taut.

@grimmy @rasterweb laser cutter stencils might work better in this case too just because I wouldn’t know how much paint to spray to get the desired effect until I did it, and layers of paint would make lace more opaque each time.

@grimmy @rasterweb as an example of the kind of effect I was looking at for a guitar finish: https://www.instagram.com/reel/C0NAUptye0W/

@mathiasx @grimmy If you have the patience (and don't mind weeding) cut and apply vinyl, paint, then remove vinyl. Otherwise you can do laser cut stencils, mylar or other materials.

@rasterweb @mathiasx good call

@rasterweb @grimmy have you ever done a rigid stencil with posts to stand off the surface to be stenciled, so that it gets a little “overspray” through the stencil, making it a bit fuzzy?

I don’t have an example of this, but I know some people do the opposite with a burst finish where a shape held up off the body blocks the spray in the middle and causes that gradient past the edge https://4.bp.blogspot.com/-nKNbdryilOY/Wgi-IUocp7I/AAAAAAAAGSs/bkYkoJXN_FMZyDgJrk0nqCDoyb_EV1xPwCK4BGAYYCw/s1600/20170716_222615.jpg

@mathiasx @grimmy I’ve done cardboard stencils, attached to the surface with rolled up tape pieces and gotten a sort of soft edge/glow when spraying.

@rasterweb @grimmy very cool! I’m wondering if I could 3D print something upside down on the printer, that raises a stencil off the guitar body a bit to get fuzzy gradients. I would keep the pattern simple, like diamonds or retro-Formica-boomerangs. https://i.pinimg.com/originals/8a/a7/85/8aa78500094dc6f2bed5fc4dc006de85.jpg

@mathiasx @grimmy Definitely worth a try!

mathiasx, 23 days ago

@rasterweb @grimmy I’m guessing it only needs a little gap to get fuzzy edges that are nice. Otherwise I’ll have to worry too much about angles and not spraying too much.

@rasterweb @grimmy I’ll do some tests with cardboard as well — thanks for that idea! Before I go down the path of modeling a stencil in OpenSCAD or (haven’t learned it yet!) Fusion360

@mathiasx @grimmy I would do the 2D part in Inkscape, save as SVG, then import into OpenSCAD, extrude, and add the posts.
