Train Shirts and Travel Quilt

I'm currently working on a couple of gifts. I'm embroidering shirts for my friend's 2 & 4 year old boys. The 2 year old's is finished except for sewing it back together. It has a cute wooden toy train embroidery. The 4 year old's is a work in progress. Slow progress. I found a wonderful embroidery of a realistic steam engine. When I test stitched it, the embroidery was too dark to look right on a navy blue shirt. Next I'll test it with lighter colors. It has 50,200 stitches and 29 color changes and takes hours to stitch out. It's a gorgeous design and will be worth the time. I'm just afraid that the new colors won't work right. Then it'll be back to square one.
The other project is a travel quilt for my sister and brother in law. They've been all over the world, so I'm embroidering various countries and landmarks. The background will be a couple of world map fabrics. It will take a long time to finish, but a joy to work on.
Soon I have to make time to do some love quilts.
