I've been using Hobbyist Decals for my scale model builds and have been really impressed with the results.
The decals are easy to work with and settle nicely on the model surface.
The designs also add a lot of realistic detail to the finished build.
I especially like the variety of aircraft, military, automotive, and other modelling subjects available.
Sharing this because I think fellow scale modellers might find their decal range useful too.

Apply decals carefully for a clean and realistic scale model finish.
Start with a smooth, clean surface before placing the decal.
Use water to gently release the decal from its backing paper.
Position it accurately and remove excess water with a soft brush.
Let it dry completely for a neat, professional-looking result.
