i love the quilt top - you've been putting up some beautiful work lately - you must have a muse sitting on your shoulders.
i always have such a hard time following directions to the letter. i would do the bubbles but not as many as the pic on the pattern nor would i use their lay out.
i would start with a large circle towards the bottom left - i can't really give you a size because scale is always off in pic vs. real life - but lets just say a 6 inch circle for example.
then i would cut a 5 inch, a 4 inch, a 3 , a 2, and a 1.
then i would lay them out on the quilt top kinda forming an undulating S - but a soft shape not a perfect example of an S.
if the scale is wrong for 6 circle to swirl from bottom left to the top right then do a 7, 8, etc - until you have the shape and flow across the top.
i think it will add an element of vertical flow since this pattern is such a strong horizontal flow.
so any way - now that i redesigned your quilt and gave you tons of extra work - you should do whatever you like because in the end you're the one living it
:D
