Welcome To KnitsThatFit

On this website you will find information and support for the KnitsThatFit apps and also links for some PDF knitting patterns.

The KnitsThatFit apps create custom knitting patterns, and have many advantages over conventional printed patterns.  There are two KnitsThatFit app – one that creates sweater patterns, and one that creates hat patterns.  Both apps have been available for iPhone and iPad users for more than 6 years, and KnitsThatFit Sweaters is now available to Android users too.  If you’re wondering what the KnitsThatFit Apps can do, you can find an overview towards the bottom of this page.

We are aware that some of you may have been using Bellish* – another app that creates knitting patterns – which has now shut down.  The KnitsThatFit Apps are a great alternative and have many advantages too.

(*Please note that we do not have any connection with the makers of the Bellish app!)
