Before buying MOC instructions, confirm the exact donor sets, additional parts and figure contents, then compare them with the usable inventory you own. Treat the download, physical bricks and any separately purchased minifigures as separate project costs. Do this before dismantling a set or assuming that a design can be built from one box.
An October 7 medieval MOC discussion includes a collector considering dismantling existing sets and replies mentioning designs with multiple donor sets. An October 6 sourcing question comes from someone who bought instructions before working out how to obtain the bricks. These individual discussions show why the materials check belongs before purchase; they are not measurements of demand or evidence that a supplier is trustworthy.
Separate the purchase from the project
Read the exact offer: a digital file, a physical parts kit, a finished model or a combination. Check what you receive, how it is delivered and whether a parts list is available for review. A photograph of a completed model does not specify the selling unit.
For example, BrickVault's FAQ states that its purchases are digital instructions and parts lists, not physical products, and that minifigures are excluded from its parts lists. That is its stated offer. Another creator or retailer may sell a different package, so check the particular design rather than applying one seller's terms to all MOCs.
Make an exact donor-set record
For an alternate build, write the donor set identifier and required number of copies. Ask whether the design uses only that inventory or needs additional elements. “Uses parts from this set” and “can be built using only one complete copy” describe different requirements.
Check whether the inventory includes spare pieces, stickers, printed elements, optional substitutions or separately sourced parts. If the donor set remains assembled, decide whether you actually want to dismantle it. An owned set can be available in your collection without being available to this new build.
Compare the requirement with the components you can locate. Similar-looking parts or colors should remain unresolved until the designer confirms an acceptable substitution. Record a substitute as a proposal; do not silently treat it as the exact listed element.

| Project line | Required | Usable inventory owned | To source or confirm |
|---|---|---|---|
| Instructions and file format | ________ | ________ | ________ |

Keep the source parts list and the designer's clarification beside the sheet. Use one row per unresolved element when necessary. A total piece count cannot show which particular part prevents you from starting.
Check whether the figures are part of the offer
Ask whether the displayed characters are included in the purchase, listed as required parts, suggested separately or used only for the scene photo. Then check the selling unit for any separate figure set. Six figures, six different designs and six loose components are not interchangeable quantities.
If you are choosing a separate cast, the six-knight retail set specifies six ABS figures with helmets, plumes, toy spears and shields. The White Knight Wagon display set is a different physical purchase, including twelve figures, two horses, the wagon, pictured accessories and base. Record the whole contents of the item you intend to buy.
The 12-book accessory set can be considered separately for a reading-room scene. These retail examples are not verified donor inventories for a particular downloadable design. Confirm the required fit and contents with the designer and the relevant seller before adding an item to your materials list. Our included-parts guide explains the contents terminology.
Compare the complete sourcing plan
- Check access to the download. Confirm the file format, delivery method, revision and support contact before paying.
- Identify the essential gaps. Prioritize parts needed for the core structure before optional scenery or alternate colors.
- Prepare the physical order. Match part identifiers, colors, condition and quantities to the confirmed list. Ask about acceptable alternatives before changing it.
- Compare the full checkout totals. Include each supplier's shipping, minimum-order conditions, currency and any applicable checkout charges. A low price for one part does not describe the whole project cost.
- Record what is still unknown. Leave unresolved availability or delivery dates as questions. Do not schedule the build around an unconfirmed arrival.
Keep digital-purchase terms separate from the physical seller's returns and replacement process. For a Minifig Muse retail item, consult the current shipping and returns and replacements pages. Those policies do not describe another creator's digital download.
Prepare the first building session
Read the instructions far enough to identify the first structural stage, then gather those parts in a separate tray. Confirm the donor inventory before dismantling it and keep a record of where parts came from. If the list still has an essential gap, resolve it before combining your collection into a new build.
When the materials plan is clear, use our six-knight display guide for character arrangement or the display-case planning guide for equipped silhouettes. Those scene-planning articles do not replace a designer's building instructions.
Common buying questions
Does an alternate build need no extra parts?
Only if the particular offer says so and its required inventory matches the complete donor copies you can use. Confirm extra pieces and substitutions before relying on that assumption.
Should I buy all the figures shown in the scene?
First distinguish required components from optional scene characters. Add the figures you want as separate lines when the design does not include them, and check their equipment space.
Does Minifig Muse provide the instructions for these examples?
