I did this pattern for a box card to put inside all my card of the game Race for the galaxy. The final result is not good, i start with a bigger base then needed so i have adjusted on way. As i am too lazy to do a new one, i have decided to keep this ugly version, but the pattern is ok.

The pattern allow to carry all card of the game but feel free to adjust the height, width and depth as you want.

I have added the chart of the simplistic rocket also.

The gauge doesn’t mater, the pattern is in cm not number of stitch.

Materiel :
Crochet hook 3.75 mm
Worsted yarn
Tapestry needle
Button
