A method for holding an item, the method comprising:

• providing a storage holder comprising:
• a base member;
• and
• a vertical member supported by the base member and that defines a plurality of apertures, wherein the apertures are spaced apart in a substantially vertical direction, and wherein each aperture defines an upper surface and a lower surface that are aligned in the vertical direction and spaced apart by a first distance;
• and
• fitting a locking feature of an item retainer within a selected one of the apertures, wherein the locking feature defines a base, an upper arm and a lower arm for holding the respective item retainer to the vertical member, wherein while fitted in the selected aperture, the item retainer is moveable between a first position and a second position, wherein in the first position a lower surface of the base contacts the upper surface of the aperture, wherein in the second position an upper surface of the base contacts the upper surface of the aperture, wherein in the first position is lower than the second position;
• raising the item retainer to the first position and positioning an upper portion of an item in relation to the item retainer such that the upper portion of the item is held by the item retainer;
• and
• positioning a lower portion of the item in relation to the base member such that the lower portion of the item is held by the base member, wherein the item is in a stored position when the item retainer holds the upper portion and the base member holds the lower portion.
