You asked...
Take the piece you have and lay it on the floor or as large a bed you have. Now take the squares that match the two diagonal light "stripes"( upwards toward the right) and continue laying those patterns out for a ways / say six pieces more. THINK JIGSAW PIECES. then take some more pieces that match more of the pattern and continue adding them to the right and slanting upward.
Continue solving your quilt "Jigsaw puzzle" until you
have a whole quilt top, filled with diagonal lines of squares of color.
Once, you get it solved, try to find a place it can stay until you get it sewed together.
You can pin all the pieces to a large sheet, and then you will be able to roll or fold it up for storage between times of working on it.!
Parts of the pattern are mirror images, which complicates it. Once, you see the whole design pattern, you will think "how easy"!
Please look up the old AMISH SUNSHINE AND SHADOW quilt pattern, as a guide.
I strongly reccomend that you ask an older experienced quilter to help you lay the pattern out.!
Because I do not know who you know... maybe ask at a quilt shop- or meeting or even church! It is a beautiful pattern.
Hope this helps....It is hard to describe something like this, and hard to understand until you have seen it.
Like the chicken-and-egg idea!
