Using your wooden form or a tin (as shown in the photo), cut the top and bottom of your picnic basket from the woven material, leaving about 1/4 inch of extra fabric on all sides. Dampen the material and shape the top and bottom of your basket over your chosen mold.
Needlework canvas has a lot of sizing which loosens when dampened, allowing you to shape the canvas over a form. Hold the canvas pieces in place with a rubber band, or a piece of string, until they dry.
Carefully remove the shaped canvas pieces from the form.
