You can also put one of those little packets that comes in a shoebox with a new pair of shoes.

Me too! Even have some in the garage. It ends up smelling musty after a few years but it's quite usable after washing.

Why not toss silica jell packs in the bottom of the tote. They will keep the moister out of the totes.

That's a great idea. I had been buying pillowcases from those linen discount stores and they've gone out of business. Some times I have even given the quilt in a pillow case so it will get stored correctly.

I have been storing in cedar chest for years till I ran out of space, no its plastic boxes with silica packets inside, never had mold, and I am in South Fla, HUMID! You could try wrapping individual pieces in white tissue such as comes with clothing, and storing on shelves. In order to identify, photocopy piece of fabric, on back side write the amount of fabric in cut, this way you don't have to unwrap to see or measure

I also store in plastic tubs. Some have been there forever. No problems here.

I store mine in the plastic tubs in the basement and never had a mold problem. But they are not really airtight. But I do leave a zip lock bag open a bit for air circulation, as I have found that the bags so seem to be airtight (I suppose for good food storage!) and they pack better if some of the air can get out.

Have your hubby drill some holes in the top of the boxes and maybe a few in the top of the sides to let the boxes breath. and let moisture out.

Do you mean Damp Rid? It works best, but you do have to empty the collection container from time to time.

DEFINITELY NOT DAMP RID! These are the little white packets about 1 inch by 1 1/2 inch that say silica gel and often come in shoe boxes, sometimes purses, they absorb moisture and keep stuff from molding!
