Rarity/ ?missing sketches!

It's a normal day in Ponyville, everything's fine... but not for Rarity... Rarity has discovered something terrifying: her sketch chest... is empty! All the dress sketches, ideas for a new collection, fabric sketches—have disappeared without a trace. What to do! Rarity has searched her entire house and found some clues—it's one of the dressmakers from another settlement! You and your friends are off to pick up the sketches!

In Ponyville, it's a normal day: Rainbow Dash is flying, Fluttershy is talking to animals, Twilight is reading books, Pinkie Pie is having fun, Applejack is picking apples, and Rarity has noticed that all the Iskiz are missing! She's been researching... She's found many clues that point to the city. Rarity gathered all her friends and told them everything, and they're all going to town to get the Iskiz.
One seamstress snuck into Rarity's house and took all the Iskizis, and Rarity didn't know where she was yet, but she knew all the signs.
