Part 1: Small Text (The 5mm Rule)

Explain that a needle is a physical object, not a laser beam.

• The Problem: If you try to sew text smaller than 5mm (0.2 inches), the needle holes are so close together that they punch a hole right through the fabric.
• The Result: Instead of a clean letter “A,” you get a “thread ball” or a literal hole in the shirt.
• The Fix: You must simplify the logo, remove the tagline, or switch to 60-Weight thread (as learned in Module 3.04).

Part 2: 3D Puff (The “Cookie Cutter” Rule)

Explain how 3D embroidery actually works using foam.

• Mechanism: We place a thick piece of foam on the hat. The needle acts like a “Cookie Cutter,” slicing the foam away to leave the raised shape.
• The Rule: You cannot use Puff on thin lines or complex details.
• Why? If a line is too thin, the needle will shred the foam into dust instead of cutting a clean edge.
• The Limit: Puff works best on Block Letters and simple shapes. No serifs, no tiny details.

Part 3: The “Tagline” Trap

Sales reps often over-promise taglines on hats.

• Reality Check: A client might ask for “Est. 1998” on a hat. On the actual product, that tagline might only be 3mm tall.
• The Outcome: It will be illegible.
• The Protocol: Always measure the smallest text before accepting an order to avoid production failures.
