I personally would like the diversity of different borders of the blocks...keep the variety going. Would be beautiful!!
Now, for the color thingie you have....here's what it is to do ...if you have a stack of picked fabrics for a project....you can look thru the cool or warmer color slide of that thingie..and, if you have too much of the same color family it will literally dissappear by viewing at it:)Really! You need differences in color..or everything would be blah...and, have had that happen in a color selection and once looking thru that viewer...it was like 'duh'! And, I fixed it:)I had 2 that were too close and by looking thru the viewer there were no definate lines to which one started or stopped..Whenever you buy a jelly roll or a line of fabric...those choices have been taken care of for you:)
I'm anxious to hear what you decide and am looking forward to some pics of that decision. Beautiful fabrics! SKeat
