What would be a great gift I could make for my teacher ?

Hmmm am no good at making stuff so can't help you there. But if you don't have the time to get around to it, you could check out a handcrafted Wall Art or jewelry box if your teacher is a woman or a man's wooden chest or accessory box. I gave my teacher a handcarved Wall Art from MarqART and she loves it! Here, take a look.
