Harley Quinn
~4wThe Suicide Squad Harley Quinn: a customized red and blue satin bomber jacket, distressed "Daddy's Lil Monster" tee, sequined shorts, dip-dyed pigtail wig, smudged dual-tone eyeshadow, and an oversized foam mallet. This is a beginner-intermediate build. The jacket and wig are the two skill checks. Covers 7 components, 12 materials with cost estimates, a 10-step build plan across 5 phases, and a realistic 4-week, $90 to $280 budget.


Sung Jinwoo
~7wSolo Leveling's Shadow Monarch in his iconic default hunter outfit: a long black coat with purple inner lining, structured shoulder armor, fitted pants, and dual daggers. This is an intermediate hybrid build that combines garment sewing with foam armor crafting for the shoulder details, plus prop work for the daggers. The coat and its glowing purple lining are the make-or-break detail. Includes 7 components, 19 materials with cost estimates, a 15-step build plan, and a realistic 5-7 week, $120 to $320 budget.


Captain America
~6wThe star-spangled Avenger in his Endgame suit: scaled chest armor over a tactical blue base, a white star emblem, red gauntlets and boot details, a foam cowl helmet with ear wings, and the iconic round shield. This is an intermediate build with repetitive detail work on the scales and some prop-making for the shield. Covers 7 components, 12 materials with cost estimates, a 12-step plan across 5 phases, and a realistic 6-week, $150 to $400 budget.


Tanjiro Kamado
~6wDemon Slayer's water-breathing hero, built from the green-and-black checkered haori down to the hanafuda earrings. The haori is the signature piece, it needs clean seams and a pattern scale that reads on camera, while the black wig requires burgundy-dyed tips and structured front bangs. This is an intermediate build for someone who can sew straight seams and follow a wig styling tutorial. The forehead scar and leg wraps add the finishing touches that take it from a costume to a character. 8 components, 15 materials, about 6 weeks, $120 to $350.
