Fabric

 is a block material in Build A Boat For Treasure. It was obtainable in the 2018 Easter event from a Purple Egg. It is typically used as a carpet. It is now obtainable from the shop (300 Gold for 50 Fabric blocks).

It is also obtainable from the Dragon Quest, Skeleton Boss Quest, and The Cloud Quest. Each quest (excluding Skeleton Boss) awards 5 blocks and the Skeleton Boss Quest awards 0-8 blocks. Another method of obtaining it is by buying the Plane Blocks Set for 4000 gold.

The player used to be able to redeem the code, "code fashion" (10 Fabric), but that code has expired.

Trivia

 * Due to an error in the shop, players were given 50 Fabric blocks instead of the advertised 100 when it was on limited sale on 7/19/19.
