I used my airbrush on this dog collar (the black letters were done with a regular paint brush)
I am no expert- but really enjoy the finishes that are possible. Daubers, sponges and rags dont work for me- no control. You will find the tool maddening at times. Air pressure, clogging, tip drying etc. Practice- and read as much as you can. YouTube videos are awesome. Use old t shirts and paper to practice.
Start with light coats...you can always "add more color" if you decide your piece needs it.
Experiment with dyes and color- on this one I used full strength Fiebings saddle tan as a base. Mixed up some other colors for flowers etc.
I do use alcohol for mixing regular dye ( haven't used the low VOC) Also use alcohol for airbrush clean up...works very well. seals haven't been an issue.
Have fun!
