Appropriate virtual gifts for professors?

This semester has been pretty rough because of COVID, I'm sure for many people. 

I'm especially grateful towards a couple of my professors for being so kind and accommodating towards me, and I feel like a nice email isn't enough to express my gratitude. Would a virtual $10-15 gift card or something be appropriate? Not sure how that works, maybe Amazon or something? 

Any other ideas for free/"handmade" gifts also welcome! I just want to do something a little "extra" to show my gratitude.

No, these gifts would not be appropriate.  The optics would be bad.  Many professors (esp. at public universities, but also at many private universities) are specifically prohibited from accepting gifts from students and from students' families.

Just send an email expressing your appreciation.  That is so much more valuable than a tchotchke.
