That looks really neat! I suggest making a really COLORFUL shop made out of all different type of wool! You can make a really colorful rainbow wool pattern. That would be neat!
Beacons. As your shop becomes more successful, you can buy more beacons, to expand your shop. It doesn't have to be all beacons, but the goal should be to amass as many beacons as possible. Become a beacon collector. See if you can outdo qwerty. Good luck
