Remember you don't have to make these blocks fancy!! There are tons of great transportation fabrics out there, you can make wonky log cabin blocks, nine patches, or other regular style blocks with some great fabrics. Or the block above that has the spaceship over the city, that's super simple without having to paper piece a block, you could do something similar to make a car driving on a road or a tractor on a farm. Be creative!! Paper piecing isn't the only option by any means!!
Cheers!
