Made by The Creative Bride

We make and use these card blanks ourselves at The Creative Bride, so we understand how important the card quality really is. A good card blank needs to feel substantial, fold neatly and provide a reliable base for printing, layering and embellishing.

Each blank is made in-house from the same smooth 300gsm card we use for our handmade wedding stationery. The cards are carefully cut and creased before being packed with coordinating envelopes. This allows us to maintain the quality we expect from the materials we work with every day, rather than simply offering a standard pre-packed product.

Heavyweight 300gsm Square Card Blanks

The sturdy 300gsm card provides a reliable base for printed designs, stamping, handwritten details, layered panels and lightweight embellishments. The square format is ideal for wedding invitations, save-the-dates, evening invitations, thank-you cards and handmade greeting cards.

White or Ivory Square Cards

Choose white for a clean, contemporary appearance or ivory for a warmer, more traditional finish. Both colours have a smooth surface and are supplied with coordinating envelopes.

Printing and Decorating Your Card Blanks

The blanks are supplied flat, making them easier to print before folding. If you plan to print directly onto the card, check that your printer accepts 300gsm stock and supports the 250 x 125mm flat sheet size. A rear or manual feed may work better on compatible printers, although printer capabilities vary.

Decorate your cards with satin ribbon, paper flowers, glitter card, stamps or layered printed panels. We recommend testing one blank before printing or decorating the complete pack.

What Size Are 5 x 5 Card Blanks?

These cards measure approximately 125 x 125mm when folded and are commonly described as 5 x 5 square card blanks. The coordinating envelopes measure approximately 130 x 130mm, providing a little extra room for the finished card and any lightweight decorative layers.
