3 and 5 are nice, particularly no 3.... but please don't use the bright yellow... it kills it...

I love the last one!

I like those also. I especially lean toward #3. Perhaps a narrower sashing would be interesting also.

I vote for the last one!

If you feel as if the tan background is too dark, how about making 15 new blocks with a lighter tan. Then alternate the 15 new blocks with 15 original blocks. Lay them out alternatively and then you will see a nice (subtle) secondary pattern emerge. So you'll have six original blocks with dark tan left over..... Use them on the back or make a pillow case or a bureau scarf! It still really isn't too late.

I vote for #3

red one looks great

I vote for the red, I think it adds a lot of interest to the blocks.

I like 3 or 6 the best.

I like the gold color.
