Welcome from Australia.
I have EQ7, in which you can draw up a block and print directions for rotary cutting, and it tells you how many pieces of each color you need to cut - & if some are reversed. If a quilt is created you can print out the amount of fabric needed. For a whole quilt using all the same blocks you will need to multiply that number of each piece by how many blocks you need to make. But it will not give you that number for the whole quilt. EQ8 may offer better, I don't know. Perhaps someone here who has this version will chime in and comment.
You should have a look at Bonnie Hunters website & blog. She has quite a few free patterns to download with directions that would help you figure it out. Many of us look forward to her mystery quilt that usually begin at Thanksgiving.
