Lesson 1Threads, needles, and reinforcement supplies: thread weight, topstitch thread, needle sizes for domestic machines, rivets, bartacks, webbingGrasp how threads, needles, and supports team up for solid seams. Learn to pick thread strengths, topstitch threads, needle sizes, rivets, bartacks, and webbing fit for home machines and bag weights.

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

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

You will map body panels, straps, pockets, flaps, and openings, choosing areas needing form, flow, and avoiding thick, hard seams.

Check cotton lawn, quilting cotton, and polyester linings, thinking of fraying, sewing ease, cleaning, and bag form and use effects.

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

Compare zipper kinds, magnetic snaps, clasps, toggles, and buttons, and learn to choose sizes and spots fit for each bag design.

Explore support stitches, stress-spot aids, and interfacing plans that stop strap breaks, seam rips, and shape loss over time.
