What You Need Before You Start
Before building your first ita bag display, gather these items:
- Your ita bag — if you haven’t chosen one yet, see best ita bags for beginners
- An insert board — foam board, plastic canvas, or fabric insert cut or purchased to fit your window’s interior dimensions. See ita bag size guide for measurements.
- Your items — enamel pins, plushies, photocards in sleeves, acrylic stands
- Locking pin backs — strongly recommended for valuable pins. Standard butterfly clutches fall off during daily bag use.
- Optional: washi tape or fabric background for the insert, small scissors to trim insert edges
Step 1: Choose Your Theme
A strong ita bag build is cohesive. Before pinning a single item, decide what connects everything in the window:
- Single character — all items feature the same character (classic oshi bag format)
- Single series — one anime, game, or group, all characters welcome
- Color palette — items in a shared color scheme regardless of fandom
- Multi-fandom — deliberate mix tied together visually by style or background
Pick one before you start. It is easier to build a focused display than to place items randomly and hope it looks intentional.

Step 2: Prepare Your Insert
The insert is the board inside the display window. It holds your pins and plushies in place.
Measuring: Measure the interior dimensions of your display window — not the outside of the bag. The insert needs to sit flush without bowing or rattling.
Insert types:
- Foam board — lightest, easiest to pin through, slightly compresses over time
- Plastic canvas — stiffer, pins stay at consistent angles longer
- Fabric-covered board — most finished appearance, pins go through fabric into foam
Optional background decoration: Apply washi tape, fabric scraps, or printed background paper to the insert before adding items. This makes the space between pins look intentional rather than blank.
Step 3: Plan Your Layout Before Pinning
This step is the most important and the one most beginners skip. Lay the insert flat on a table and arrange all your items on it before pushing a single pin through.
Layout principles:
- Focal point first. Place your most important or largest piece in the center. The viewer’s eye goes to the center of the window. Your best item goes there.
- Build outward by size. Arrange medium pieces around the focal point, smaller pieces filling the outer edges.
- Leave breathing room. A build 70–80% full looks more intentional than a build packed edge-to-edge. Leave space to add new finds later.
- Mix heights and types. A plushie centered between flat pins looks more dynamic than all items at the same depth.
- Take a photo before pinning. Once you’re happy with the arrangement, photograph it on the table so you can recreate the layout if items shift.
Step 4: Attach Your Items
Work from the center outward, starting with your focal piece:
- Enamel pins: Push the pin post through the insert, then attach a locking back on the other side. Use locking backs on valuable pins; standard butterfly clutches on cheaper pins.
- Plushies: Use a ribbon loop through the insert, tied loosely around the plushie’s torso. Or use Velcro dots between the plushie’s base and the insert surface. Do not press pins through plushie fabric unless the plushie is designed for this.
- Acrylic stands: Most acrylic stands sit on a base. Place the base against the insert and secure with double-sided tape or a small Velcro dot.
- Photocards: Place photocards in clear top-loader sleeves and pin through the top of the sleeve to the insert. Do not pin directly through the card.
Step 5: Close and Wear
Once all items are secured, slide the insert into the display window and close the zipper or clasp. Check that the window closes fully — if the insert is too thick, items near the edges may prevent the zipper from closing.
Before wearing: hold the bag upside-down over a soft surface and shake gently. Any items that fall have loose backs and should be re-secured before the bag goes out. Better to find this at home than at a convention.
Pro Tips from the Community
- Use locking pin backs on everything valuable. Standard backs cost nothing to replace; irreplaceable limited-edition pins don’t.
- Don’t overfill before a convention. Leave empty spots intentionally — you’ll buy new pins at the con and want somewhere to put them.
- Two-layer builds. Place tall items like acrylic stands at the back of the insert and flat pins in the front layer. This creates depth without crowding.
- Background first on themed builds. If using a printed or fabric background, apply it before any items. It is impossible to add background material cleanly after pins are in.
- Swap builds seasonally. Remove old pins carefully using a prying tool (a paperclip bent flat works). Clean old pin holes in foam board with a drop of white glue to reset the surface for the next build.
Frequently Asked Questions
How long does it take to fill an ita bag?
A first build with 15–25 pins takes 20–45 minutes including layout planning.
Experienced collectors can rebuild a 40-pin insert in under 20 minutes.
What insert material is best for beginners?
Foam board is easiest to start with — pins slide through easily and it is cheap to replace
if you make mistakes. Plastic canvas lasts longer once you know your layout.
How do I keep a plushie from falling over inside the bag?
Use a ribbon loop through the insert tied gently around the plushie’s waist, or Velcro dots
between the plushie base and insert. Avoid heavy plushies in bags with shallow windows
— they’ll sag forward and press against the PVC.
Can I use my ita bag insert for photocards?
Yes — place photocards in clear top-loader sleeves and pin through the top of the sleeve,
not directly through the card surface. A canvas or fabric insert works better than plain foam
for holding sleeve pins securely.
How do I remove pins without damaging the insert?
Hold the pin firmly from the front and use pliers or a prying tool to loosen the back.
Pull straight out, not at an angle. In foam board, fill old holes with a small drop of
white glue and let dry before repinning.
My bag window won’t close over my build — what do I do?
The insert is either too thick or the items are too tall. Try removing the tallest item,
or flatten the insert slightly by pressing it under a book overnight.
For deep items like acrylic stands, angle them slightly toward the center.
