Here are some things you can do to prevent vintage pattern envelopes, tissues and instructions
from becoming brittle and disintegrating during storage.
from becoming brittle and disintegrating during storage.
When making repairs NEVER use regular tape or adhesives. Use acid free tapes and or adhesives, preferably archival quality.
To help prevent brittleness and disintegration you can spray pattern tissues, envelopes and instructions with "Make it Acid Free" a ph balancing aerosol spray. Please spray lightly, don't saturate.
Store each pattern in an archival quality acid free plastic sleeve.
If you want to add a cardboard backer make sure it is acid free cardboard.
Store patterns upright and loosely (don't pack them in tightly) to encourage airflow and prevent further damage.
If you live in an area with high humidity you can add a silica gel packet to your storage container or drawer (silica is toxic so keep out of reach of pets and children). It's best to store patterns in metal storage drawers or acid free containers.
Don't store your patterns in extreme temperature environments.
Never store patterns in a damp basement, it will encourage mildew growth.
Here's a link to info about the spray, you can find it on Amazon.com and I believe Joann's Fabric also sells it.
