etsy. Theyre just little knitted squares, i use whatever wool is left over in my stash, which i glue ribbon too and then stick onto bought card blanks. I get these white card blanks from hobby craft. I used to attach a dymo embossed happy birthday to the cards but my dymo has broken (bad times) so i found a dymo font online and printed it onto glossy photo paper, cut it out and stuck the wording to the card. Done! Really easy but very cute i think.
I also loved how all the little squares looked stacked up next to each other, a little knitted rainbow!
The card set are available to buy in my shop on etsy, other combinations to follow hopefully, or message me if you intersted in anything specific.
