Paper goods such as stickers, zines, and art prints are print and cut in my home. I use a Canon printer, and Canon or Red River photo paper. Stickers may be cut with a plotter machine, or by hand. Zines are cut with a guillotine and stapled by hand.
Charms and DTG pillowcases and mousepads are outsourced, usually to Vograce (CN) or ZapCreatives (UK). You can read Zap's enviromental policy here: https://zapcreatives.com/pages/environmental-policy
I use recyclable and reusable packaging as much as possible. Items are packed in unwaxed glassine paper bags. Those are then packaged in plain paper mailing envelopes. Occasionally, I may recycle branded plastic shipping envelopes.
Shane and I pack everything by ourselves We spend the weekend organizing orders, and ship out on Monday via USPS. (weather and COVID permitting)
