As Nadège told you the Tween Spirit "screwed-up" sweater is a must-have for children this winter and will be soon available for adults. The technique we use to design holes in the sweater is called "ladder stitch". It's one of the most enjoyable/scariest one in the world! You can really feel like you are destroying everything you've created/knitted and that's quite crazy! Don't be too precious with your knit! Have a look at our tutorial video, it's so simple and strongly recommended by our style team!
