I'm a designer by trade but now run a digital fabric print studio working with all sorts of talented designer makers across the world.
Fabric and printing and everything really, I'm kind of one of those people who knows in a little bit of information about everything as I'm a sponge for information.
Don't point out the flaws in your project, be aware of them but one persons perceived flaws can be another's gems.
Cheerfulness, seriously my friends have honestly told me this. Every situation however shitty will have a silver lining, you just have to look for it.
