Lesson 1Threads, needles, and reinforcement supplies: thread weight, topstitch thread, needle sizes for domestic machines, rivets, bartacks, webbingUnderstand how thread, needles, and supports work together for strong joins. Learn to choose thread weights, topstitch thread, needle sizes, rivets, bartacks, and webbing for home machines and bag weights.

Learn when to pick canvas, denim, twill, upholstery cloth, or leather options for style and performance.

You will check stiffness levels, flow, fusible fit, and pressing heat so your bags keep shape without bubbles, burns, or twists.

You will map body panels, straps, pockets, flaps, and openings, deciding which areas need shape, which need flow, and how to avoid thick, stiff joins.

Check cotton lawn, quilting cotton, and polyester linings, thinking about fraying, ease of sewing, cleaning, and how they affect bag shape and use.

Compare woven and non-woven fusibles, sew-in canvas, hair canvas, foam, and cotton duck, and learn when each best helps shape, corners, and fittings.

Compare zipper types, magnetic snaps, clasps, toggles, and buttons, and learn how to pick sizes and places for each bag design.

Explore support stitches, stress-spot helps, and interfacing plans that stop strap breaks, seam splits, and twists over time.
