I'm sure any moderately experienced home cook could produce these pretty cookies. I'm of the opinion that, if one takes enough time and follows a recipe, most recipes can be produced within a reasonable facsimile of what was intended.
They're beautiful cookies and I would imagine take a bit of time and patience to produce. If you're game, I say go for it!
