How to redo cabinet doors with designs?

If you want to paint, perhaps spray painting the doors that have the wheat shocks with thin coats so the pattern does not fill in may do the best

You could use some wood putty ( I use Bondo wood putty) to fill in the pattern, then sand it down to make it smooth, then a good coat of primer, then paint.

Cool design, assuming you still want to show up.... I have never been good with spray paint myself, so if I was going to paint, I would try a brush. You could always use a damp Q-tip to get globs out of little design. If you are a patient painter you could always do a contrast color on the wheat design.

You will need to lightly sand first though. You don't need to bring to bare wood except like where that inset border is really scuffed get it pretty smooth.

After removing all hardware and doors-

You could fill in the pattern divots with wood filler, sand and repair all the nicks and bumps, wash well with deglosser, prime, paint, and seal for a whole new look.

OR

You could sand all the finish off, including in the pattern divots, do any repairs needed for nicks and bumps, and restain and seal your cabinets. For a little change up, you could enhance the design with a darker stain.

Hope that helps

Wood burner?

Looks like custom knotty pine cabinets with chip carving in the door. They also look pretty well worn. Fill in the carving with wood putty and sand smooth.

Make sure they are clean and dry. Remove the doors and hardware. Mark the doors and cabinets with tape where they go. Lightly sand the doors and cabinets to remove any gloss and roughen the surface for paint with 120- to 220-grit sandpaper. Use a tack cloth or damp rag to remove dust after sanding. Prime with a stain blocking primer like Zinsser 123, KILZ,or BIN and have it tinted to the color of the top coat. This will prevent dark or stained surfaces from showing through the top coat. Acrylic, or water-base, paints are low-fume and clean up easily with water. Alkyd, or oil-base, paints require good ventilation because the paint contains solvents that can irritate your lungs and make you feel sick. Alkyd options require mineral spirits for cleanup, but they provide a hard, durable paint finish. Whichever you use, buy the best-quality paint you can afford for a lasting kitchen cabinet finish. Seal with at least three coats with a water based polyurethane. Use a small foam roller and foam brush for a smooth finish.

I would paint the trim one color, and where the design is, another.

Sand inside the carved design lightly with a small scrap of 220 sandpaper to scuff up and even out color, then fill the design you want to keep with wax by rubbing a candle into it. Then sand, fill any imperfections with wood filler, prime with killz and paint the entire cabinet as you wish. Make sure you you've removed any excess wax outside the carving. When paint is completely set, remove the wax & you can either paint or polyurethane the designs with a small brush to restore the intricacies. I'd love to see what you end up doing!

Are you familiar with glaze ? It's not quite paint as it is a bit more see thru, like a french manicure with sheer pink polish that you can see thru a little bit. You could keep the cabinets the current brown and use a little black or antique glaze to bring out the dimple / bumbs of the wheat design. You just brush it on, wait a minute and wipe it off. The stain will pool in the dimples and dents and look darker. You can also paint white or cream cabinets and use the antique glaze on top of that.
