Boao Sublimation Garden Flags 20-Pack 12x18 inch Blank Polyester DIY Flags for Heat-Transfer

Boao 20 Pieces Sublimation Garden Flags are 12 x 18 inch blank polyester banners designed for DIY sublimation and heat-transfer projects, sold in a bulk pack so you can customize seasonal or event-specific mini lawn flags.

These blank garden flags come ready for printing or heat-transfer decoration, offering a consistent 12 x 18 inch size that fits most standard mini flag stands. Constructed from lightweight polyester, the flags are durable for repeated outdoor and indoor display and packaged in a set of 20 so you have extras for variations, gifts, or replacements. They arrive folded; a light ironing is recommended before printing to ensure smooth results and a clean transfer.

How do these flags handle sublimation and HTV transfers?

The fabric is polyester, which makes it suitable for dye-sublimation and many heat-transfer vinyl (HTV) techniques. Because these are single-layer flags, the print works best on one side and some color can show through to the back depending on inks and transfer method.

• Polyester surface supports vibrant dye-sublimation colors
• Compatible with HTV when using appropriate temperatures and pressing time
• Single-layer construction — expect possible show-through on reverse side
• Recommend ironing flat before transfer to remove creases

What size and fit should I expect for lawn stands and displays?

Each flag measures approximately 12 x 18 inches (30 x 45 cm), a common mini-garden flag dimension that fits most standard flag stakes and mini poles. Always check your stand opening and orientation before producing printed graphics to ensure your design aligns correctly.

• Standard mini flag dimensions: 12 x 18 inches
• Works with most mini-flag poles and garden stakes (stands not included)
• Folded in shipment — press flat before printing for accurate placement
• Landscape orientation best for typical garden flag stands

How durable are these flags for outdoor use and multiple seasons?

The polyester fabric is lightweight yet sturdy enough for repeated seasonal or event use, though outdoor longevity depends on weather, mounting, and care. For longer life, display flags in sheltered spots and bring them indoors during heavy rain or strong winds.

• Polyester resists tearing and keeps shape well
• Best to avoid extended exposure to severe weather for color longevity
• Machine wash gently or spot clean; air dry to preserve prints
• Extra quantity in the 20-pack gives usable backups
