Use scissors to cut the bottom of your laundry basket. If the edges are sharp where the plastic has been cut, use coarse sandpaper to smooth them out.
Spray paint the laundry basket. We used gold but any shade of brown would work.
Tie two pieces of twine from the front of your basket to the back of the basket to act as shoulder straps to hold the basket at your child's waist level. You may want the child to stand in the basket and hold it while you measure the length of the yarn so you can cut it to the best length.
Tie the balloon to the basket. For an added touch, dress your little one in stripes and a scarf and tie "sandbags" on the sides to store treats.
