You will need an ice cream tub
and a shower cap
Cut the ice cream tub below the rim as shown. and punch two holes ready for adding the handles. I did this with a single hole punch.
Fit the shower cap over the ice cream tub and secure it with elastic. When fitting nicely put some ribbon just above the elastic. Sew or glue the ribbon in place then remove the elastic.
Thread a large needle with ribbon. Feel for the punched holes and feed the needle through them to make handles as shown. This should keep the shower cap in place
Put ted in his new carry cot.
Now I just need to make him some bedding.......
