Hiya.
I suppose I should point out the following, as on this forum there are all kinds of users, from the experts to the very beginners:
it's great you are happy with the maki you received but it is not a good maki. It might be serviceable but it's not as good as described.
It is a necessary statement as beginners might actually think it's good.
There is a huge difference between "serviceable" and "good".
Here are some reference pictures.
This is done by JKOO. It is very tight and absolutely serviceable. Yet, there's no hishigami (it had some extremely tiny cardboard triangles which didn't help at all, were present just as an excuse to justify the +$20 hishigami service) and diamonds are very uneven.
Serviceable? Yes.
Good? Nope.
This is done by Zsey. It is tight and shows better hishigami, with correct thickness. Diamonds are also a bit uneven but overall it's a pass.
Serviceable? Yes.
Good? Not exactly but a pass.
This is done by me. Again, it's serviceable and has proper hishigami (could have been a bit thicker tho, I made them too thin) but diamonds are uneven. I'm quite awful at maki and hope I'll improve with practice.
Serviceable? Yes.
Good? Absolutely not.
This is a Citadel. Diamonds are small but mostly even. Hishigami have the right thickness. Ito is tight enough.
Serviceable? Yes.
Good? Yes. This one is good enough. And by no means "slightly worse". Actually a much better one.
This is Motohara. As per Citadel, very tight ito, proper hishigami, even diamonds.
Serviceable? Yes.
Good? Yes. But it's not "a slight better job". This too is "a much better job".
It's all a matter to put things into proper scale:
I believe on a scale from 1 to 10 where 1 is a souvenir wallhanger and 10 is a Japanese Master, my wrap is a 3, most Chinese wraps are a 3, Zsey is a 5, Citadel and Motohara are a 7 and Josh Marlan is a 9.
