You can make Minecraft papercraft toys by either purchasing an officially-licensed kit or by downloading printable patterns from a website such as Pixel Papercraft. In both the officially-licensed and fan-created versions, you can find patterns for popular Minecraft characters, such as Steve and Creepers.
With several options of Minecraft papercraft toys available, you can try several and see which suits your needs.
The officially-licensed Minecraft papercraft kits are available at many retail stores and online. There are many of these sets, including the Deluxe Overworld set, the Animal Mobs set and the Hostile Mobs set. These pre-printed sets are on heavy cardstock and include stickers and tape. These kits are available at many price point and allow you to get started quickly.
The fan-designed materials at Pixel Papercraft are patterns that you can print on your choice of paper and cut out. While this option may be more labor-intensive, you may find more unique Minecraft papercraft designs than in an officially-licensed product. For example, one available project allows you to create a papercraft toy of Minecraft's crafting table, complete with the user interface from the video game, while another allows you to create an entire animal pasture with pigs and cows.
