this is one place they show a 'crazy quilt" pattern, You start with a pentagon, 5 sides, and start adding to that to create a square. i thought maybe your treasures could be cut into a pentagon and youcould go from there. I saw it demonstrated on "sewing with Nancy" but cannot find the episode on her website nancyzieman.com.
The first thing that came to me was a layout like T-shirt quilts. I made one for an elderly lady, embroidered relevant names. Here's a couple ideas: http://www.goosetracks.com/T-Shirt%2...tructions.html
(I really like that 2nd one down, lap quilt)
Sounds like fun, good luck.
Perhaps an Attic Window pattern, since many have a black background maybe a light and medium for the windows in solid colors, or simple prints, and boarders in her favorite colors.
Or maybe snowball pattern.
Ask at your local quilt shop. I know at the one I like to go to the ladies are very good to help and have a much better eye than I do when it comes to that.
Does your Aunt have a favorite color?(somehow it cut that sentence but left the Does)
I would lay them out to see if anything stands out, like the color of the frogs eye to use as a background color. You mentioned most of have black background you continue that theme or contrast with a white. Does What about making them into their own blocks like in a crazy quilt with your 'loves' as the center?
