Make Your Own Bags for Life
If you’ve got a sewing machine you can easily run up a bag using any strong-ish fabric you have to hand, otherwise plain linen bags are available from Hobbycraft (you can buy them cheaply in bundles - it’s also an excellent children’s birthday party/ school summer fair activity). Decoration, depending on the age of the child, can take the shape of embroidery - sketch out the design first, and then go over it using a simple backstitch - or painting, using Eco brush pens by OkoNorm, available from Conscious Craft.

You could even use what you find to create a piece of art that can be added to in months to come, using more found treasures. One person’s trash, as the idiom goes . . .
