As you know, now-days lot of products are planned or designed with an artificially limited useful life
so it will be no longer functional after a certain period of time - this is a built-in obsolescence. Why would be an except the flexible laundry plastic bucket? When you ever used this you know about an half year daily usage it will be very close to final dead. The weak point of this construction which is probably originally designed: the handles.

They will be longer, more plastic and weak after the several transport of heavy laundry and finally they
will be broken. You can say goodbye your bucket and re-buy a new one.. Or not. Here is an easy solution to re-fix the weak point of this type of buckets: make the handles stronger with the usage of twine.

Step 1: Cuttting Handles and Make Holes

You easily cut the two handles.
Cut two hole under the original handles where the bucket is enough strong yet to hold the weight of wet clothes (see images).

Step 2: Twist and Node

Twist a stronger twine from the one-line twine (I have used the most simple 3 three line twisting).
Place the two twisted twines on both side of the bucket and fix them to the bucket with nodes.
(When you want the cut part to make it more refined you can slightly burnish it with fine sandpaper)
