Choosing fabric for a project can really be hard. 
 Im linking up with Jess at Quilty Habit as part of her Sewing With Certainty series.   
I tend to buy fabric and decide what to use it for later.  I buy what I like.  This got me into trouble when I had an abundance of large scale multi-color prints.  I try to buy with more diversity now.  Medium and small scale prints, tone on tone, and two color too
Recently I started a BOM class doing Kaffe Fassett's Imari plate quilt from his book Quilts of Sweden.  Its a medallion quilt and I decided to go very scrappy and use my extensive Denyse Schmidt stash.  But how to begin?  The idea of a rainbow stuck in my head.
I started by sorting by print size and type.  As you can see I spread fabrics all over the floor sorting.  I leaned toward a rainbow effect the first week with the center block.
Looking at all the piles of sorted fabric I carefully chose 8 colors for the petals.  I paid attention to the numbers of colors in each print and the scale, trying to be somewhat consistent.
I went with the dark gray background to make the other colors really pop.  I chose the medium gray leaf print for the center.  Many others fussy cut centers but I wanted the petals to be more of the focal point  
I was very pleased with my center.  The next BOM was a pieced border.  My challenge was what fabrics to pick .  I needed a center, middle and background fabric.  It also had to mesh with the center.  I carefully picked two fabrics to go with each color I had chosen for my rainbow.  I also picked a coordinating lighter shade to use as the background.  25 different fabrics to acheive that rainbow border.  I also had to coordinate inner border.
I was very happy witht the little logcabins for the border.  And Look.  I think they came out just right.
And here is the carfully assembled border.  I cant wait to plan the next one.  I know it will be a challenge.  Im trying not to repeat fabrics.  Im saving the large scale florals for larger borders where I can fussy cut them.
I hope you find inspiration from this project.

she gave paint chip numbers to match up your fabric too.
