McGargantuette

I'm making a quilt for my daughter and want to figure out how to add some meaningful/sentimental words and lines of text to the backing. The sandwich is basted but not yet quilted. I want the text to be pretty small, so you have to look close to see/read it.

I only have a straight-stitch Juki (and a Janome Magnolia with 18 stitch choices, but no embroidery options).

I'm neither good nor fast at embroidery by hand, but perhaps this is my only option.
Any other ideas or suggestions about how I might be able to accomplish this?

Thanks !
