Baby strollers are used for several years, from newborn to toddlerhood. They must stand up to spills, messes, and common wear and tear. Many manufactured liners do not last through a child's outgrowing the stroller, let alone last through several children. Parents can replace the liners by making their own out of durable, washable and attractive materials. Stroller liners can be simple padding layers that are laid in already present stroller liners or can be the replacements for these manufactured liners entirely.
Select your material. Consider using wipeable plastic or vinyl or polyurethane laminate. These fabrics are flexible and durable and can be washed easily. Check local fabric stores for cute prints that will stand up to wear and tear and spills.
Measure your stroller. Mark all curves and all slots for straps and leg holes. Some strollers have removable seating pads. If yours does, trace around the existing pad onto a large piece of paper such as newspaper. Clearly indicate where you'll need to insert slots for straps and fasteners, both on the front and back of the liner. Mark the same pattern on the inner padding of your liner to ensure the strap slits will line up.
Cut your material and pin it together. Layer your two outer fabrics with the padding in between. Pin the right sides together. In sewing, "right" sides are the sides of the fabrics that have the print or design on them. Your stroller liner should have an outer layer with the print facing inward, the padding layer, and the second outer layer with the print still facing inward. Place straight pins approximately 7.5 cm (3 inches) apart around the outer edges of the liner. Put the liner in the stroller to check fit and size. Make any adjustments to the liner.
Sew your cover. Sew using a sewing machine approximately 6 mm (1/4 inch) from the edge. Leave a 7.5 cm to 10 cm (3 to 4 inch) unsewn area to facilitate easier turning right side out. Turn the liner. Sew the opening closed by hand. Add all fasteners or adjusters such as buckles or hook and loop closures. Press your liner using an iron on medium-low setting to remove wrinkles and give a neater appearance. Place in stroller and fasten using buckles and fasteners.
