Small display crates and tray-style boxes often need repeated gaps: a little reveal around a slat, a steady space between dividers, or a clean shadow line beside a label rail. Measuring every one of those gaps with a tape can slow the work down and still leave small differences.
A clean cardboard spacer is the low-pressure fix. Cut one strip from stiff packaging, trim it square, and write the intended use on it with pencil. The spacer does not need to be fancy; it only needs to be straight enough to repeat the same distance without compressing under your fingers.
Use the strip during dry-fit before glue or fasteners are involved. Set the first part where it belongs, slide the spacer against it, then bring the next rail or divider up to the same edge. If the look feels cramped, make a new spacer instead of trying to remember a half-change by eye.
Cardboard is useful because it is gentle on finished faces and easy to replace when it gets fuzzy. Keep it away from wet glue, and do not use a swollen or dented spacer for final layout. Once it loses a crisp edge, cut another one and keep the measurement honest.
This tiny habit is especially helpful when a crate is meant to sit in a shop window or on a market table. Even spacing makes handmade work feel intentional without making it look machine-perfect.
Practical takeaway: cut one labelled cardboard spacer for repeated display-crate gaps, use it during dry-fit and marking, and replace it as soon as the edge gets soft.
