Great for you Smiley_face!
Cardboard boxes work and so does this...
I have used it for years! This year (a few days ago*lol) took the bottom out and moved it to fit in my driveway design.*lol
Have fun!
I buy potatoes that look good and have tiny sprouts on them or you can just keep them in the bag indoors ,dry and nearly dark room temps and the sprouts will take off.
Onions work that way too ,only,they use light.I just keep them in my hanging basket in the DR and let them grow a bit, cut the sprouting part off and plant*lol
If you let them (onions) flower you will get pretty blooms! Some may be perennials.
Oh...Garlic gloves will grow too!
