I sewed the Men's Roller Coaster Tee (MRCT) from Duck Butt Designs. I love the patterns by Duck Butt Designs because of their colour blocking. Anything with colour blocking is great isn't it?
The two types of fabric with stripes is actually the same fabric. For the lower piece I used the right side of the fabric and for the other piece I used the wrong side of the fabric. I adapted the pattern slightly by taking in the sides with 1 cm. Luckily I thought of this before finishing the t-shirt because the larger piece with the stripes is actually 1 piece and there is no side seam in that pattern piece.

Fabric: red and black fabric is from my own stash, I bought the fabric with the stripes at Cares Stoffen.
