Here is my short tutorial if you want to make it on your own. Once you make the first one, making more takes less than 15 minutes.
Materials: Felt, velcro tape, coordinating embroidery thread, needle. handmade charm, scissors
Step 1: Cut your felt to 6"x 4" (16 cm x11 cm) -for a rectangular jewelry bag
I used this size, because business cards fits inside the bag very nicely.
Step 2: Fold the felt lengthwise, to where there is ~1.5" is left for the top part.
Step 3: Stitch each side with hand. Keep the tension on the thread very loose for big stitch look.
Step 4: Fold the top part outwards less than 0.5" and hand stitch the folded line horizontally.
Step 5: Place a felt flower or a button in the middle of the top closure and hand stitch it securely
Step 6: Place the velcro at the center of the top and bottom parts.
Add a bit of more cuteness with a handmade charm..
Step 7: Va laaa... Now, open inside and enjoy your cup of sparkle...
