Hey Dotty,
All you have to do is to sew your fabric strips together then bring the bottom up and sew it to the top strip. After that cut them the width you want (you'll have loops) Take a seam out then move down one block and take out a seam on the next loop. On the third loop move down one more row and take out that seam. You can do it, I first practiced on 12 1 1/2" x 18" strips. I just cut 1 1/2" off 12 different fats and sewed them together. It's the same process as doing a Bargello.
