Our #1 Tip: Say “YES” to Samples First
Ordering a paper brand that you have not seen in person?
If this is for a wedding or special event, this is not the time for a blind date!
- Available on most product pages
- Choose the 1-Sheet or 1-Envelope option
Why Samples Are Non-Negotiable
Years of experience have taught us that ordering paper sight-unseen is risky. Here’s why we always recommend starting with samples:
- Feel the Quality — Experience the exact weight, texture, and finish in your hands to ensure it matches both your project’s needs and your creative vision.
- See True Color — Online images can be misleading due to screen settings, lighting, and photography. Paper can appear to be a perfect match on a screen, but look different in real life. Samples let you see the real shade and how it coordinates with your wedding or event palette.
- Prevent Costly Mistakes — Test print on the actual paper before placing a large order to avoid expensive reprints.
- Save Time & Money — Skip the frustration, returns, and reordering process by making the right choice the first time.
Don’t Rush the Details
- Planning a beautiful project takes time. Starting early gives you room for design decisions, proofs, and unexpected delays.
- Ordering physical samples is quick, easy, and the smartest first step.
