I put all my snowball and alternate blocks on the design wall.
Then I realized the problem.
Leftovers. Clearly I cannot count. I hate leftover bits. I don’t have any more of these prints here, so I tried adding more white at the ends.
This isn’t working, but it led me to my solution.
Stay tuned.

I may have a few of those prints if you just a few, depends on size you need.
These are so pretty. I love snowball – very versatile technique. Glad you found a solution to your conundrum!
