⚡ At a Glance
  • Paper Quality: 140lb/300gsm cotton cold-press paper with textured surface and strong absorbency
  • Best for: Hobby artists, card makers and hosts creating handmade invitations and thank-you notes
  • Not ideal for: Large-format artworks or projects that need bigger sheets than 4x6 folded size

Sixty foldable cotton cards with matching envelopes, each card 4x6 inches folded. The heavyweight 300gsm cold-press stock soaks pigment while reducing warping for small-format watercolour work.


Vibrant, even washes - thanks to 140 lb/300gsm cotton cold-press paper

Cotton fibres in the cold-press stock hold pigment and water evenly, while the 300gsm weight resists excessive buckling. The textured surface helps granulation and brush control for watercolour techniques.

Colours blend and layer cleanly on the surface, making small compositions look polished. Less warping means fewer interruptions and neater finished cards ready to post.

Post-ready stationery - with 60 envelopes and back-adhesive seals

The set contains sixty envelopes that use a back-adhesive sealing strip rather than a peel-and-stick or lick seal. The included matching envelopes are sized for the folded 4x6 cards.

No extra glue or tape is necessary to send finished work, so creating and posting invitations or thank-you notes is quicker. Generous envelope count supports multiple events or batches of cards.

Compact canvases for small projects - with 4x6 folded and 8x6 opened dimensions

Each card measures 4 x 6 inches when folded and 8 x 6 inches when opened, offering a postcard-sized front and a larger interior for messages or extra artwork. Both sides of the card are blank.

Ideal for practice pieces, quick commissions and personalised greetings that fit standard postcard holders. The fold gives space for a written message without covering the painted front.
