The Modern Collage T-Shirt quilt  also has no sashing but it does have a 3 inch border.  The T-Shirt squares are a mixture of different sizes.  They are then sewn together to make the size block then they are sewn all together.  This particular style is best used when you have a lot of graphics. Graphics that is small in size. For example a front logo or a long and thin arm graphic.  This quilt will take more shirts because of all the piecing. It will also be smaller in size due to no sashing.  Just a note on this particular quilt, there are times when backing fabric or T-Shirt fabric will be added to the blocks.
