I find that a lot of people are a bit apprehensive about preparing Matcha because of the whole ceremonial connotations with this tea. They shouldn't be. What's the worst that can happen? Your crema is not rich enough - no biggie. It is too weak - add more. Too thick - thin it down.
The point is that whilst Matcha making can be an art and a ritual, this shouldn't scare you away. I openly admit that my whisking action needs a little work and I sometimes stare enviously at the perfect crema on someone's Instagram but Matcha is actually a really easy tea to make if you follow the steps in this video. Grab a jam jar and get shaking!
An extra tip: my mother has a Matcha everyday and she whips it up cold in one of those nespresso milk frothers (with water) - it works really well if you have one!
