They are an ideal gift, and a great size to pop into a card. I have personalised two (third one ready to sew) for my sisters. I printed out their names onto fabric and then used this as the lining.
I could not take a photo of the inside lining, and the velco closure covered up most of the top of the flap. However here is an example of one that is waiting to be sewn (I need to purchase some white velco today) to show you what the lining looks like.
Just one strip of 3" fabric, cut into 4 pieces and you too can make one of these. Will I share the link to the pattern, you bet! Here it is ...Key Ring Card Holder
I think this will be what I will sew as the thank you gift for the Breast Cancer Dinner this year. They will look great made up in the pink fabric, pretty and practical.
Do I now admit I have approximately another dozen cut out, waiting to be sewn? Let me know if you get hooked on making these.
