The stretch vinyls (1860,1867,1868,1869 and 1871) are unique fabrics. The
process involves bonding a thin sheet of stretchy vinyl to nylon/lycra®. The
nylon/lycra® is stretchier than the vinyl. If the size you choose is too
small and the fit is too tight the two materials will separate (delaminate).
Order one size larger than your normal size. These fabrics are for costumes
and special occasions. They are not for sports and exercise activities. In
time they will begin to look like leather as they crinkle. Eventually they
will delaminate. Accept that, ok ?
Fabric 1870 is a non-stretch vinyl. We will only use it to make T3 and B3
styles.
