I bought this June Taylor pressing board on one side and cutting mat on the other. the pressing board side is gridded, that what i use for 1 inch grid. lay you lightweight fusible interfacing on it with the fusible side up, I put down my 1 inch pieces on it lining them up. I lightly press them to adhere them then mist with water or a wet pressing cloth to firmly adhere them by iron/pressing them again. It helps if you cut your pieces just a smidge smaller for ease of folding this for sewing. This is how i made the mini quilts in my avatar.
