I am in the midst of designing a boys quilt (small) for my expected 6th great grandchild. I am thinking of doing bright batik colors (in blocks of 9") and then adding a very large silhouette of a boy with a balloon.
My questions to all of you knowledgeable quilt members is: 1) How to keep the appliqué "soft" as is the quilt, 2) Best "soft" stabilizer, 3) Will FMQing over the silhouette lessen it's quality, 4) Ways to ensure that heavy laundering will not destroy the silhouette. 5) Best "soft" black fabric for the silhouette (I was thinking Kona but it is a bit heavier than I believe this project should be. I really would appreciate your input for this project. Thank you.

Here's my design:
