What a wonderful holiday for you!
I think you've got it ... your first layout of the new round and add I to the right of #1 ... it'll really help the lights pop against the darks when put together. Or does that give you one too many? .... then stick with what you have!!
Now for that coffee by the lake ... dash to the store for your new rotary cutter!
Hope you'll show us progress pics at each stage, as you make it!!
(remember the thread recently of the lady in Hong Kong that showed us pics at each stage ... felt like we were making it with her, starting as you had with the fabric selection)
