"Haunted" is from the Lizzie*Kate Mystery Sampler, it was the bonus pattern in part 1. And "Spells" is from the 'Just Cross-Stitch' Halloween 2012 issue.
I've backed both with a glow-in-the-dark spider web fabric.
As for my Mystery Sampler, 'Very Scary'..... I still have not decided whether to rip / frog those stitches yet or not.
