Thanks!
You know, I read all different directions and looked at all different pictures, then I simply went to town.
I cut out the fronts, then stabilized with woven fusible stabilizer, and then trimmed them into nice rectangles.
The pieces of Tshirt were all so varied in width, so I laid them out on the floor, in columns, till I got a pleasant design.
Making all left edges align, I found the largest width block, and then chose a cotton novelty print to 'fill in' the width of the narrower blocks (note the flames, or batman)
After that, it was a simple assembly by column and then all columns together to make the whole!
Not daunting at all, once I thought it through...
