Shopping for Art Stuffs

I wanted to try a special pencil named "Pitt oil" andso I bought one.

The first one is like a reason for the latter, so "so" fits here better.

Later I walked around the shop watching among, looking through several kinds of papers, and finally I boughtbuying four watercolour books, too.

1. " 'round " is usually seen as an informal shortening of "around".

2. Here "buy*ing* four books" parallels (basically just takes the same form as) "look*ing* through several kinds". It sounds smoother, and it's not grammatically wrong either.

These books, how I tolas I've mentioned, are especially meant for watercolours, with sheets a bit thick,lightly thicker sheets, of exactly of 200 g/m2 (grams per square meter), also namcalled grammage.

"named" didn't really fit (near the end)

They are very good for drawning and paint in anywhere because they are not very big.

You can put it in and carry in your pocketyour pocket and carry it around.

I forgot to tell,mention, I got three of them are fors gifts in this Christmas.

1. "tell" works here, but doesn't fit quite right. "mention" is a better choice.

2. I can't tell if you meant to say (in the last part): "I bought them for *someone else* as gifts" or "*I* got them as gifts." (I corrected to the second option.)
