If I receive a postcard, what does that mean? What can I do with it? When I get 3 postcards is that when I get a Wishlist pattern?
Ribbot has a postcard giveaway, so the postcards automatically takes you to it and enters you.
Here’s link to the giveaway - you can see more there: July Postcard 💌 Ribbot's Giveaway!
If can, be sure to mark who helped provide a solution
Lucky Sunday and the Postcards are two different events.
On Sundays, look for the Lucky Sunday post and follow the directions to enter. Usually it involves typing the phrase ‘I’m in 
’ into the thread. The winner of that event will (typically) get a pattern from their wishlist.
The Postcard is a different monthly event with prizes that change. On your Homepage, look in the top corner for Ribbot and click on him to Feed him. Every 7 days (less for Ribblr+) you can Spin the Wheel. A Postcard is one possible outcome. It will be posted on the month’s Postcard thread for an entry into that event. You’ll have to read the opening post each month to see what the prize is.
Julys postcard winner gets 10 Gems per post 1 in the July postcard thread
This month you can get free patterns with just 1 gem. Some in the future may be more gems.
