o.k. we have come to the cross roads , and need some advice , we would like to know everyones take on this question! back drops !painted or background sheets? , i mean there are some really nice already back drops out there! so as modelers do you think it is better to paint your city scenes or to use ready made ones? as well as the sky's!
