Choosing among leather hardware, patterns & care can mean solving four different problems: replacing a shoulder-bag strap, cutting a waist bag, shaping a crossbody, or adding snaps. The smart pick depends on whether you need a finished component or a cutting template-and whether its dimensions and format suit the project. Here is the quick way to separate the choices.
Quick take
- For a finished shoulder-bag replacement: Real Leather Handbag Purse Strap Wide Bag Strap for Shoulder Bag Replacement offers a detachable, 1.4-inch-wide strap with black and gold hardware.
- For a waist bag pattern: Waist Bag Sewing pattern leather craft die cutting template 20x13x6cm defines a finished bag size and 4mm stitch space.
- For a crossbody pattern: Leather Craft Bag Sewing Pattern Set - Acrylic & Kraft Stencil for Crossbody Bag uses a Kraft paper template with holes.
- For closure hardware: Black Line 20 Snaps - Regular & Short Posts - Leathercraft Hardware - SLC combines two post lengths in a 100-pack.

Decision matrix
Need a component you can attach to an existing bag? Start with the detachable shoulder strap. Its listed strap/handle format separates it from the three craft-focused choices.
Need a pattern for a specific bag shape? Choose between the waist bag template and the semi-circular crossbody set. The former gives a 20x13x6cm finished size; the latter is centered on a crossbody handbag and includes holes in the Kraft paper template.
Need closure hardware rather than a cutting guide? The Line 20 snap set is the direct match. It includes regular and short posts, with stated leather-weight ranges that help connect the post choice to the material thickness.
Need to keep the project format simple? The strap is a finished item, while both patterns require cutting and sewing. The snap set is hardware in a 100-pack, so it makes more sense when several closures are part of the plan.
Product notes
Real Leather Handbag Purse Strap Wide Bag Strap for Shoulder Bag Replacement

If you need a finished replacement rather than a cutting guide, this detachable shoulder-bag strap is the clearest fit. It is made from cow split leather and measures 30 inches long by 1.4 inches wide. That width is intended to distribute a bag's weight across the shoulder, while the black-and-gold hardware gives the listed version a defined look. The fixed 30-inch length is the main limitation because it gives you one specific strap dimension to plan around. It is also a strap/handle, so it does not address a new bag pattern or a snap-closure requirement. Choose it for refreshing an existing shoulder bag with a broad, detachable strap.
Waist Bag Sewing pattern leather craft die cutting template 20x13x6cm

This template is aimed at a waist bag with a finished size of about 20x13x6cm, making it the focused choice when that shape and scale match the project. The English version and 4mm stitch space give the cutting guide a clearly defined layout for leather craft work. A practical limitation is that an oversized pattern may be cut into two or three pieces, with a joint line shown; that can add a joining step before cutting or sewing. It is a pattern rather than a finished bag, strap, or closure component. Pick it when the goal is to create a waist bag and the stated dimensions are more useful than a general handbag outline.
Leather Craft Bag Sewing Pattern Set - Acrylic & Kraft Stencil for Crossbody Bag

Choose this set when the project calls for a semi-circular handbag or casual crossbody shape. The listed format is a Kraft paper template with holes, and the sample size is 18x20x7cm. That makes it a defined cutting-and-sewing guide rather than a replacement part or closure kit. Its limitation is its specific focus: it guides a crossbody handbag project, so it is not the waist-bag template and does not supply a finished strap or snaps. The Kraft paper material also makes the template format central to the purchase. It suits a maker who wants a handbag outline with the pattern layout already established.
Black Line 20 Snaps - Regular & Short Posts - Leathercraft Hardware - SLC

For a project built around closures, the Black Line 20 set is the direct hardware choice. It includes regular posts and short posts, with the regular 3/16-inch post listed for 5-7 oz leather and the short 1/8-inch post listed for 4-5 oz leather. The 100-pack format suits work involving multiple belts, straps, bags, holsters, or everyday leather projects. Its limitation is quantity: a 100-pack is a substantial format to plan around when a project needs just one closure. It is also the highest-priced choice in this comparison. Select it when Line 20 snaps and the two post lengths match the construction plan.
Final recommendation by use case
- Replacing a bag strap: Choose the Real Leather Handbag Purse Strap for its detachable format and wide shoulder-bag profile.
- Making a waist bag: Choose the Waist Bag Sewing pattern leather craft die cutting template when its defined finished size and stitch layout suit the design.
- Making a crossbody handbag: Choose the Leather Craft Bag Sewing Pattern Set for its semi-circular handbag focus and Kraft paper pattern format.
- Adding multiple closures: Choose Black Line 20 Snaps when a 100-pack and regular/short post selection fit the project.
- Letting price lead: The crossbody pattern sits at the lower end of the listed range, while the snap set sits at the higher end, with a $35.74 spread between them.
