Thomas prints with red sashing and a red print border and backing!
IOur youngest (now 16) GS LOVES red. Always. I made him a red and white Bear Paw. Since we live in the Smokies Mtns where bears abound, and he was born here ... just fits!

Maybe you could make a red and white quilt, and a Thomas Pillow?

I would get a Thomas panel and start adding red borders. What ever will make him happy I'm sure.

Red with Thomas the Train is perfect for a child.

KIDS LOVE BRIGHTS! KIDS LOVE RED! REGARDLESS OF BOY OR GIRL
i would find some wonderful primary colors....good strong bright red, blue yellow, green, orange and purple...and some LIME for good measure...
i made a little guy a thomas the train quilt a few years ago- it had a fire=engine red background...with bright royal blues- blacks- yellow...he loves it! his mom complains he has really outgrown it- every time she tries to pack it away for years from now he finds it and gets it back out- he was 4 when i made it= he's almost 12 now---and he does not care if Thomas the train is no longer of much interest- that quilt remains an important part of his life!

Great. He will love it

Of course you can use any color you or he wants. That's one of the real realy pleasures of quilting. One of a kind, tailored to the recipient!

I have red in my grandson's room. He does not actually live with me but I decorated his room for when he comes and spends the night with "NaNa".

Oh red!!! What a happy color for a child!!! I'd get a Thomas panel or even Thomas fabric and add borders in the blue, black and RED to match. I think it would turn out lovely, fun and happy.

sure why not?

I think red is perfect for a boy. You might even find a pieced train pattern.
