Prevents slippage between materials with a nap and the lining. Materials with a nap tend to shift in one direction due to the nap rubbing against itself. The same applies to sewing materials with a nap and the lining. Slippery materials can also cause the top fabric to slip, leaving only the bottom fabric being fed, resulting in slippage. By inserting each fabric piece between the plastic dividers, the fabrics do not rub against each other until just before sewing. The seam allowance width can be adjusted by sliding the seam allowance guide.
