Bundle Concept
Each kit is bagged together in a resealable clear cello bag with a Purple Inkwell Studios branded header card (printed on your home printer, folded over the bag top). The signed card goes inside. The print is rolled or placed in a backing board sleeve alongside the bag. Total kit presentation looks like something from a curated Etsy shop — not a con table afterthought.

Revenue Projection — 30 kits
If you sell 20 of 30 kits at $38 bundle price + 10 individual prints at $20 each = $760 + $200 = ~$960 gross revenue from this kit alone, on a $194 investment. That's nearly 5× return on materials at a modest sell-through.

~2 min per sheet. Load 18 sheets at a time. Total run ≈ 60 min.

Bag each kit: sticker sheet + button + mini journal + signed card into cello bag, attach header card
The 11×17 print lives in its backing board sleeve separately — buyer chooses design at the table.
Prep
Sleeve all 30 prints in backing boards (or clear plastic sleeves)
Group by design, label each stack for easy table access during the con.
Prep
Create price tags / display cards for the table
One card per product type showing price. Include bundle pricing prominently. Black cardstock + white ink pen = on brand.
Prep
Do a full quality check — flip through every journal, check every button, inspect every sticker
Anything off-center or damaged gets pulled. You want zero embarrassments at the table.
Prep
Pack for transport — prints flat in a portfolio, kits in a box, table display items separate
Don't let prints ride loose in a bag. Flat portfolio or art tube for transport.
