my new hobby is making jewelry

I started to make some jewelry these days.
I bought some parts for jewelry in Japan when i went to there.
Making jewelry is really fun and makes me so happy when I finished my job :)
Already I I already made more than 30 stuffsthings like earrings, necklaces, and bracelets.
i'm wondering if i could sell them ... it would be better ;)

"Already, I" is not really incorrect, but it doesn't sound natural.
In America, we never say "stuffs". If we are talking about multiple objects, we say "things".
Keep up the good work! ^^
