All

Is there a particular technique in sticking new decals on a frame? I’m impressed with custom painting topic currently running and people are clearly better than I am at lining up the decals.

Any help much appreciated

In my experience, no, just a steady hand and a steady eye

make sure frame is clean and free from any oil/grease . Warm it up slightly with a hair dryer. Apply transfer as above and use an old pair of pants to rub the sticker onto the frame
