Anything I can do to stiffen my boxes??

You can stiffen them up by placing foam board cut to size. You can purchase about 18"x24" sheets at DollarTree.....another option would be thin wood paneling cut to size.

I would attach to the basket after cutting to size. You could use anupholstery needle to attach with jute or some heavy duty thread or even fine fishing line. If you want to do the install permanently, you could use Gorilla glue, E600, etc.

Here is a tutorial on how to make strudy fabric baskets:

I agree with janice. Foan board from Dollar Tree. Has paper bonded on both sides with a foam core. About 1/4" thick. Cut with a utility knife of Xacto knife. Measure the inside if the boxes, cut the foam board slightly oversize for a tight friction fit and slip it in the against the sides of the boxes. If you want, a dab of hot glue on each foam board panel close the top will stick it against the box sides

you can put pieces of cardboard in the bottom from old boxes or even double a file folder that will help as well

You could also construct a wire frame and attach the insides to it with needle and thread.

I would cut foam board or new cardboard to fit the boxes.

I would suggest to make wire frame for this and attach to the inside of the fabric basket.

You could make boxes out of cardboard to fit inside and hold them up. :)

You could cut cardboard to fit and put inside. I did that with my car organizer.

This is what I have: EZOWare Set of 3 Large Canvas Fabric Tweed Storage Organizer Cube Set W/Handles for Nursery Kids Toddlers Home and Office - 15 L x 10.5 W x 9.4 H -Gray/Brown https://www.amazon.com/dp/B01MCYSBL6/ref=cm_sw_r_cp_api_glt_fabc_01WCB9BB7R2HSMH29XJ9?_encoding=UTF8&psc=1

id have to cut the fabric inside at the top to insert cardboard or foam core which I do have on hand.

Agree with cardboard inserts, a tight fit properly measured would give more support and structure

Can you maybe add pieces of stuff cardboard or hardboard to the bins to stiffen them up? If the expense of doing so becomes more than new ones, you might consider the latter route of new.

Hi Lisa, you can stiffen the fabric, here is a link with 6 different ways to stiffen fabric, hope it helps you out,

Put some cardboard pieces inside the walls to hold up if they won’t stay glue them with a hot glue gun

I would just pick up some plastic hangers (just like the ones in your photo) from Dollar Tree. Cut the bottom straight piece out. Use super glue or hot glue and attach it into the seams of the corners of each storage unit to make it stand up straight.

OR - get something like cardboard (from an Amazon box?) and cut to fit bottom and attach to each corner a skewer or piece from bottom of hanger or something to that effect to form a frame for inside that will give definition to your box.

Cardboard or foam board from the Dollar store slipped in as inserts will work. I knot his drives me nuts and that is what I did

You can insert card board on the inside

Hi Lisa,

The source of the problem with the fabric baskets is not so much that they are soft sided. They are not fitting or staying properly on the shelves because the shelves

1. do not provide enough support due to the space between the wires being hollow

and

2.the shelves are too shallow to accommodate the dimensions of the baskets you are trying to use. In the picture you have posted, clearly almost every item and container on the shelves is hanging over the side

Solution:

1.Remove these cheap wire shelves completely, and replace with solid wooden ones that are deeper. This will provide a firm base for the items, and one that you will be able to slide items on to, without having them fall between the wires, get caught on the wires, or hang over the sides. Wooden shelves do not require the metal struts, which will then enable you to put higher items on the shelves if you like.

2.Cut pieces of foam board to fit the bottoms of the fabric baskets. One source of free foam boards can be real estate offices, after the property has been sold, or political offices, after elections are over. The boards may have wording still on them, but as the pieces will be hidden at the bottoms of the baskets, this should not adversely affect wear.

You could use strong Cardboard or thin MDF and cut it to shape to fit internally.

Glue cardboard inside the walls. Hot glue

Heavy Card, Plexiglass, MDF. Plywood. Taped with Gaffer tape!

Make a wooden frame that sits inside the basket but the frame will give the basket more strength

Use Card or Timber or Board or Plastic cut to size.

Hi Lisa: The only thing I can think of is to use cardboard around the inside edges, as high as the bin, for stability. Put the tape for the corners on the outside of the cardboard so that it doesn't get hung up on whatever you put into the bin. Also, make the sides about an inch longer than necessary so that you can bend them around the ends and make the corners a bit sturdier. And make a floor out of cardboard, too.

Hi Lisa, you can stiffen these with starch, but new rigid baskets would give a clean look!

Cut cardboard or foam board and line the baskets.
