I really like the jewel box quilt; I'd like to make one myself. And I really love the retro fabrics.

Wow! What a cheery cherry quilt

so fun! love the fabric!

Wow, stunning!

I would start with something small, like a lap quilt or a baby blanket.  Do a simple pattern so you don't get overwhelmed.  I do a lot of hand quilting but machine stitching will let you see your progress quicker.  Just dive in and have fun with it!
