I do not know how to use 'of' when describing an amount, measurement or belonging. Here are some examples to explain what I have tried and what I want to achieve. Could you please explain the mistakes I have made?
1)I need transparent one of this a square meter sheet .
2)I need screwable one of this type of table leg.
3)I need cheaper one of this model of t-shirt.
1)The Seller showed me colorfull plastic sheets of one square meter but I told him that I need transparent a sheet. And I said this sentence.
2)I need a toilet paper holder which I can screw on the wall, but the holder they have just can be sticked on the wall. Is sentence 3 be correct?
3) I saw my friends t-shirt. When I learned its price I thought it is too expensive and I said: 'Cheaper one of this t-shirt'.
Are all uses of 'of' correct to describe what I try to say?If any of my suggestions are wrong correct them?
