Fun with Fosshape!
March 23, 2018
For Indianapolis Colts: The Exhibit, the Conservation department assisted with preparing several textile artifacts for display. The most challenging objects to prepare for the exhibit were the two Colts cheerleader uniforms. The costumes consisted of separate tops and bottoms, which would allow much of the mannequins to be seen, so the mounts needed to be visually pleasing for the costumes to really stand out while on display. The costumes also needed the support of a full form in order to be exhibited successfully and safely because even though they’re contemporary objects, they were still compromised in some areas since they had been worn during performances.
None of our mannequins were small enough to accommodate the dimensions of the cheerleader costumes, so we borrowed a form from the Indiana State Museum that we could use as a mold to create our Fosshape mannequins.
Fosshape is a non-woven polyester material that has gained popularity in the Conservation field for textile supports and mannequins. It was originally used in the theater industry and feels like a soft felt fabric at first but shrinks and hardens after being heated or steamed. Conservators like using this material because it is safe to use with collections objects and allows us to create relatively inexpensive mannequins quickly and easily.
The first step in the process was to drape muslin fabric on the borrowed mannequin to create a pattern. Once the draping was complete, the patterns were transferred to the Fosshape fabric, the pieces were cut out, machine-sewn together and the tube was slipped back on to the form for steaming.
Steaming shrinks the Fosshape around a form and once it dries and cools it hardens, creating a fairly rigid shape. The hardened Fosshape “shell” was stuffed with polyester batting and the neck and legs were capped with Ethafoam polyethylene plank. We now had our mannequins.
A gray cover was sewn to cover the Fosshape forms to provide a smooth surface and to provide an aesthetically pleasing form that allowed that colors of the costumes to really pop. The costumes were placed on the mannequins and additional padding was added where more support was needed.
Ready for game day!
