I would leave the bottom right one out in large amounts...a small amount ...It would work as the binding though.

Ok...didn't see where you are using for the Craftsy lesson...I'd put the bottom right as the strips in the wonky pound sign. ...maybe the yellow/green that is to the left of it as the solid....or the floral.

I would get rid of the two in the left and get two that are greater value difference. They are pretty fabrics, but from the photo, it looks like these two fabrics will just visually blend in with the similar colors you already have.

I'm not crazy about the brown.

Like the fabrics you chose.

I thin the yellow or gold doesn't work.

You can always use the colored dots on the selvage to see what colors match.

Love the pink & brown & may the orange - not sure if I like the rest together though

I agree, a bit of contrast would create interest and catch the eye. They seem to be of similar values -- of course that may be my computer screen too.

I personally wouldn't do the brown, but would add a blue that matches the blue in the print. I invested in a color wheel, it has saved me having to make the tough decisions about what goes with what. First, I use the colors within the main fabric, and build around that. If I need to, I go to the color wheel. Works every time. Love your color theme though. The limes and peaches go together very well.
