I'm not an expert in the art of making fake macarons, but I definitely keep trying to improve my art. I still recall the first time I tried my hand on making the life size macaron was probably sometime last year, and I was nervous as I don't use that much clay at one go creating something. But I was really happy I started because it opened up another world for me :)
As I went on creating macaron after macaron, I gathered some knowledge and I would do a few refinements every time I try making them as I think that's how I know what worked or didn't work for me.
Pay attention to the colour. The best thing about macarons is they come easily in many shades and colours, so you can almost replicate a colour or shade easily without much difficulty. But the real challenge would be, can you stick to the same colour consistency for the X amount of macarons you are making? That should be something to think about.
Points to consider:
1. If you are making them in bulk, how do you keep the colour consistency so that the whole batch looks the same? (Maybe this wouldn't be your consideration if you are only make one piece, but if you are trying to build a macaron tower, then you might want to think about this.)
2. Do you want to mix them all first before creating? Then again, what kind of clay are you using to make them?
The macarons that I've seen in real life looks moist or semi glossy, so before you actually gloss it, consider the amount you are going to use. Everything in moderation :)
Smooth or Dappled
I don't remember seeing smooth macaron shells in real life - again I'm using my own real life experiences when creating the fake macarons. There are smooth shells out there, but this depends on your personal preference.
These are the things I think about when I create life size fake macarons, and I hope for those of you who would like to give a try creating fake macarons - hopefully they give you something to think about before you start, so you can be more successful in your attempts.
Have fun making them!
