If you look at the full pattern on the "Finishing Page", of your pattern - some of your blocks will have three diff. fabrics, some of your blocks will have 4 diff. fabrics, and then some of the blocks will have 5 diff. fabrics,
I made a copy of that pattern for myself to color up as I completed putting the quilt together, and started in the bottom left corner, saw the corner block had 3 fabrics,
then 2nd Block had 4 fabrics,
3rd block in that row has 4 fabrics as well,
and 4th block has 5 fabrics
- I placed them just as seen in the pattern, and crossed off/colored - each as I completed stitching them together.
I never did figure out if there was to be some designation for "a Road", but mine worked out but only by completing it as I outlined above.
This pattern makes a very large quilt!!
I hope this may help you out. Have a great day!!
