When you RFQ custom feather flags, the line item that often stalls an agency or venue order is not print color — it is the base. Pick the wrong hardware for the surface and the flag either cannot stand on sealed concrete or cannot dig into grass without looking jury-rigged. This guide settles feather flag cross base vs spike against the live iPopupbanner catalog so your quote lines match the ground you actually deploy on.

Direct answer: which feather flag base for which surface?
On the official custom feather flags banner page, the quote form offers two base styles only: Cross Base and Inground Spike. Use them this way:
- Hardscape (concrete, footpaths, plaza pavers, sealed curb) → Cross Base with water bag. The cross base weighs about 3.8 kg; add a filled water bag for wind. The PDP notes a filled water bag around 24 lbs, and separately lists weight bags from 26–102 lbs filled with water or sand.
- Soft ground (grass, soil, nature strips, sports fields) → Inground Spike. The spike weighs about 1 kg, is a roughly 20″ solid metal stake with a swivel, and is driven into the ground. Hammer the spike section only — do not strike the spindle/barrel.
Those are the only two bases verified on the live quote form. Do not invent plate, drive-on, or tripod bases for an iPopupbanner feather RFQ.

Feather flag cross base: hardscape RFQ notes
Cross base + water bag is the default when your event plan shows asphalt, concrete, or tiled plaza approaches. Agencies booking outdoor expo approaches and storefront curbs usually land here.
- Cross base alone gives a stable footprint on hard surfaces; the water bag adds ballast for wind.
- The same cross + bag kit can also sit on grass if you need one hardware type across mixed surfaces — still weight it.
- Complete sets on the PDP include 1 custom flag, 1 pole set, 1 base, 1 carry bag (Oxford carry bag). You can also order flag-only or hardware-only if replacements are the job.
For RFQ lines, write something like: M / 10 ft · single-sided reverse · Cross Base + water bag · qty 6 · plaza curb.
Feather flag ground spike: soft-ground RFQ notes
Inground spike is the purchase-intent match when the deployment is grass or soil — trail edges, sports fields, golf approaches, park markets. The PDP describes a swivel fixture so the flag can turn with the wind rather than wrench the stake.
- Drive the long stake into soft ground; the pole seats on the short parallel spindle (offset joint), not as a tip-mount on the stake tip.
- Always hammer the spike section. Striking the spindle/barrel risks damaging the swivel.
- Spike is not a workaround for sealed concrete unless you have an approved ground hole — if the surface will not accept a stake, switch the line to cross + bag.
RFQ example: L / 13.5 ft · double-sided 3-layer · Inground Spike · qty 4 · grass sideline.

Lock size and print face on the same RFQ row
Base choice sits next to size and print option on the live form. Keep these catalog facts on the same line so manufacturing does not guess:
- Heights: S 8.5 ft (260 cm), M 10 ft (310 cm), L 13.5 ft (410 cm), XL 16.5 ft (500 cm).
- Print: Single Sided Reverse (one layer, about 70–95% reverse bleed) or Double Sided 3 Layers (two flags + blackout middle). Double-sided flags are heavier and fly less; single-reverse is the common outdoor traffic choice.
- Wind guidance on PDP: single-reverse about 30 mph; double-sided about 17 mph. Take flags in during severe weather.
- Poles are not interchangeable across heights — each height needs its matching pole kit.
- Polyester dye-sublimated / digitally printed graphics; free design service; No MOQ; free shipping window stated as roughly 5–12 days on the shipping block (step copy also notes 7–10 days after payment).
If you still need a full size and sides walkthrough, use the existing guide feather flag sizes S–XL, bases, single vs double sided. For wholesale field lists (qty, artwork, ship-to), see custom feather flags wholesale quote specs. This article stays on surface → base.
RFQ checklist: cross base vs spike before you hit send
- Surface map — concrete/pavers vs grass/soil for every placement.
- Base per line — Cross Base (+ bag) or Inground Spike; no invented third base.
- Height — S / M / L / XL with matching pole (not interchangeable).
- Print option — single-sided reverse vs double-sided 3-layer, with wind expectation noted.
- Quantity + artwork — logo files or free-design brief; approve proof before PayPal invoice.
- Carry / spare hardware — bag included with pole sets; order hardware-only if you already own poles.
FAQ
Can I use a feather flag cross base on grass?
Yes. The PDP states the cross base is suitable for hard surfaces and can also be used on grass, and recommends selecting the water bag option outdoors for stability.
When should I choose an inground spike instead?
Choose the spike when the flag will sit on soil or grass and you can drive a ~20″ metal stake. It is the lighter soft-ground option (~1 kg) with a swivel spindle.
Are feather flag poles interchangeable if I change base later?
No. Pole kits are size-specific and not interchangeable between heights. Changing base (cross vs spike) does not change that pole rule.
What wind ratings should I write into the RFQ notes?
Use the on-page guidance: single-reverse about 30 mph and double-sided about 17 mph, and plan to take flags inside in severe weather.
Next step: send a surface-correct feather RFQ
Open the feather flags banner product page, pick size and print option, then set Cross Base or Inground Spike to match each surface. No MOQ. Free design and proof before payment. That is the shortest path from venue map to a clean wholesale quote.
