Baths bombs vs. Jewellery

I've been trying to plan the next workshop today, it's on the 19th of March which is perfect for making some mothers day gifts! 

I've been trying to decide what a brilliant activity would be.... I'm thinking of choosing between making bracelet and earring sets OR beautifully packaged bath bombs.

I'm torn because not every mother may want a bath bomb 

BUT 

we've done a fair bit of jewellery making before (bling is always a crowd pleaser though). 

What would you choose? 

Orrrrrrr
