Boao Sublimation Garden Flag Blank Bulk Set

Best for bulk decoration projects or classrooms. The flags are made of polyester, light yet durable, and suitable for HTV or sublimation. Each flag measures about 12×18 inches, a standard size that fits most mini flag stands (not included). Note that printing is single-layer on one side, with the back showing through in some cases. For best results, iron the flag before sublimation to remove creases from packaging.
Who it’s for: crafters needing multiple blank canvases for patterns, kids’ clubs, or small outdoor displays. Why selected: strong material with a practical size for most standard stands and a budget-friendly bulk option. Caution: back permeation may occur on the reverse side; plan designs accordingly.
Boao 6 Pieces 3×5 Feet Blank Flags

Best for large outdoor displays and events. These double-stitched 3×5 feet flags are made from 175g silk taffeta, providing sturdy coverage for longer outdoor use. The flags are blank and ready for customization with sewing, painting, or heat transfer. The size makes them ideal for visibility at parks, school grounds, or big backyards. Limitation: material preference may affect print fidelity for certain sublimation inks; ensure testing before full production.
EZHVA 5 Pieces Double-Sided Sublimation Flags

Best for double-sided prints and vibrant displays. These 12×18 inch flags use 300D polyester with a 3-layer weave to support printing on both sides with minimal shrinkage. All edges are double-stitched, and the fabric is designed to resist wrinkling, fading, and weather exposure. Choose this if you want mirror designs on both sides or if you’re distributing flags in windy locations. Caution: price might be higher per flag compared to single-sided options.
Anglecai 10Pcs 18×12 Inch Polyester Flags

Best for versatile DIY projects and frequent use. These 18×12 inch flags are made of durable polyester and are blank on both sides for easy customization. The set includes ten flags, providing ample material for home decor, seasonal designs, or neighborhood events. Limitation: back-side permeation is possible since flags are single-layer printing per side; plan multi-side designs accordingly.
HFKPJRT 10 Pcs Sublimation Flags 12×18 Inch

Best for starter projects and classroom use. The package contains ten flags at 12×18 inches, a convenient size for sublimation, HTV, or painting. Flags are single-sided, with a blank surface ready for your designs. They’re suited for welcome signs, seasonal banners, and small yard displays. Caution: back-permeation means designs on the front may influence the reverse side visibility.
Buying Guide
What should you look for when choosing sublimation blank flags?
- Printer compatibility: Ensure the flag fabric accepts sublimation inks or HTV as intended for your project.
- Print-side orientation: Most flags are single-sided print with potential back-through; double-sided options exist and are ideal for two-way visibility.
- Material and weave: Polyester 300D or higher weaves provide durability and sharp print results; heavier fabrics hold color better outdoors.
- Size and stands: Check flag dimensions against your stands or poles. Common sizes are 12×18 inches and 3×5 feet.
- Durability: Look for double stitching on edges for longevity in wind and weather.
- Quantity: For events or group projects, bulk sets offer better value per flag, but ensure you have enough storage and stands.
How to prepare the flags before printing?
- Iron or flatten the fabric to remove folds from packaging.
- Test print on a small area to confirm colors and bleed.
- Wash and dry flags if needed before long-term outdoor use.
What printing method is best?
- Sublimation ink for polyester fabrics provides vibrant results with good durability.
- HTV (heat transfer) is an alternative for non-sublimation compatible fabrics or for layered designs.
How to care for sublimation flags?
- Gently hand wash or use a gentle cycle; avoid high heat drying to preserve colors.
- Store flat or rolled to prevent creasing and back-permeation during non-use periods.
