I've noticed a lot of online subscription based services for knitters in the past couple of months. One that has captured my attention recently is PostStitch!! Here's more information about PostStitch from their website:
PostStitch is a subscription-based service that delivers a monthly knitting project to knitters worldwide. Available in two subscription pattern options - BigStitch (adult women's accessory project) and SockStitch (adult women's sock project) - each subscription is assembled with you in mind and contains a printed pattern from a prominent knitwear designer, premium yarn, project notions, and curated extras to help you knit the project from start to finish. No matter if you have been casting on for years or are picking up a new hobby, PostStitch will introduce you to new fibers and designers, challenge you to learn a new skill, and/or add variety to your current project queue.
I haven't tried the PostStitch subscription based service yet, but am contemplating using their service after I've completed some of my current knitting projects and use up more of my yarn stash!
