To design your own greeting card, choose blank cardstock for hands-on drawing and writing, a craft kit for guided decorating, or a custom-print option if you want your artwork reproduced. The Joyberg 4-by-6-inch set is best for versatile DIY projects, while the Silunkia 5-by-7-inch cards offer a larger format. The custom portrait cards are intended for uploaded designs, and the QIAONIUNIU kit suits children’s crafts. A new-home card is a ready-made option rather than a blank design surface.

| QIAONIUNIU Card Making Kit | Kids’ guided card crafts | Self-adhesive decorative kit |
| New Home Card | Buyers who prefer a finished housewarming card | Ready-made occasion card |
Joyberg Blank Cards And Envelopes

Best for: People who want a blank card set for drawing, handwriting, watercolor, or custom printing. This set includes 30 folded white cards and 30 envelopes. The cards measure 4 by 6 inches, and the envelopes measure 4.25 by 6.25 inches.
The listed cardstock weight is 200 grams, while the envelopes are 100 grams. Both sides of the cards are uncoated, which the product description identifies as suitable for markers and watercolors. The envelopes use peel-and-seal adhesive strips.
Why it was selected: It combines a defined card size, matching envelopes, and a blank surface for personal artwork or messages. Limitation: Its 4-by-6-inch format provides less design area than a 5-by-7-inch card.
Silunkia 5-By-7-Inch Blank Cards

Best for: Designers who want more room for a larger illustration, collage, or handwritten message. The product name identifies a 20-pack of white blank greeting cards with envelopes in a 5-by-7-inch size.
Why it was selected: The larger stated format is a useful alternative to compact 4-by-6-inch cards when the design needs more space. It is a straightforward blank-card choice for a buyer who plans to create the artwork or message themselves.
Limitation: The provided product information does not specify cardstock weight, surface finish, envelope dimensions, or whether the cards are folded. Check the listing details if those features matter to your project.
Custom Image Portrait Note Cards

Best for: People who have finished artwork or a logo and want a personalized card rather than decorating blank cardstock by hand. The product name describes 100 vertical cards, white envelopes, uploaded artwork, and a folded size of 4.25 by 5.5 inches. It also states that the cards are blank inside.
Why it was selected: Uploading a design is a different way to make a card your own, especially when producing multiple copies of the same image or design. The listed quantity makes this option more appropriate for a batch than a one-off handmade card.
Limitation: This is a customization service, not a blank craft kit. The supplied information does not describe paper weight, printing options, or how a design should be prepared.
QIAONIUNIU DIY Card Making Kit

Best for: Children and families looking for a guided craft activity. The listed kit includes blank cards, envelopes, die cuts, and self-adhesive pieces, so the described assembly does not require glue. The product is presented for making handmade cards for occasions such as Christmas, birthdays, and thank-you messages.
Why it was selected: Unlike a plain cardstock pack, this kit provides decorative pieces that can help a young maker get started without creating every design element from scratch. Its listed benefits include practicing assembly, dexterity, and use of instructions.
Limitation: It is a themed craft kit, so it may be less suitable for adults seeking a completely open-ended card design or a specific professional print format.
New Home Housewarming Card

Best for: Someone who needs a housewarming greeting but does not want to build a design from blank materials. The product name describes a new-home congratulations card for new homeowners.
Why it was selected: It provides a ready-made occasion-specific alternative for shoppers whose main goal is to send a card, not to design one. It is less aligned with a fully custom project than the blank cardstock and upload-your-design options above.
Limitation: The supplied information does not state whether the card is blank inside, customizable, or packaged with an envelope. Confirm those details before choosing it for a personalized message.
Buying Guide: How To Choose Card-Making Supplies
Do you want to make the card by hand or print a design?
Choose blank cardstock if you plan to draw, paint, write, or attach your own decorations. A card-making kit is better for a guided activity with included decorative pieces. Choose an upload-your-design option when the artwork is already finished and you want matching copies. These approaches serve different needs, so decide on the process before comparing sizes.
Which card size fits your design?
A 4-by-6-inch folded card is a compact option for short notes and simple artwork. A 5-by-7-inch card gives a design more room, but check the product details for envelope dimensions and folding format. For a printed custom card, compare the stated folded size with the layout of your image so important details are not cramped.
What should you check about paper and mailing?
For handmade work, look for a stated surface finish and paper weight. The Joyberg listing specifically identifies uncoated cards and mentions markers and watercolors. If mailing matters, confirm that envelopes are included and fit the finished card. For custom printing, the available product information may not specify paper or design-file requirements, so verify those before ordering.
Frequently Asked Questions
What is the easiest way to design your own greeting card?
Start with a blank folded card, add a short message and one clear visual element, then decorate with materials suited to the card’s surface. A self-adhesive kit can simplify assembly for children.
Can I use watercolor on blank greeting cards?
The Joyberg product description says its cards are uncoated and can be used with watercolors. Other products in this list do not provide the same surface information.
Should I choose a 4-by-6-inch or 5-by-7-inch card?
Choose 4 by 6 inches for a compact card and 5 by 7 inches when you want more area for artwork or a longer message. Check envelope fit before mailing.
Are custom printed cards the same as blank cards?
No. Blank cards are designed and decorated by the buyer. Custom printed cards use artwork or an image supplied for printing, so they are better for repeating a finished design.
What should I check before buying a card-making kit for a child?
Review the included materials, whether assembly requires glue, and the instructions or steps described in the listing. The QIAONIUNIU kit is described as self-adhesive and includes die cuts, blank cards, and envelopes.
