Here at So Many Aircraft we think of scale modelers as our primary target audience.
Over the years we have written about various modeling techniques, and given advice to people either in person or on social media. Rather than having to repeat all that, the material is collected (and edited or completely rewritten) here:
Our occasional writings about models and other things can be found on the So Many Aircraft blog; older articles, under the heading "Adventures in Plastic Surgery", can be found here. We also have some artwork available for decals in case you want to print your own for your model projects, as well as some useful information about colors and paints.
We have comprehensive descriptions of completed model projects, complete with subject background, "build notes", and references.
