Blocking is an important step to undertake after knitting an item and before wearing/using the new knitted item.
Personally, I have yet to do any blocking though as I've been a tad tentative in doing so because I wasn't sure how to block. I decided to watch a few different videos on YouTube about blocking to grasp the basic concept.
I chose to post a short, concise video about blocking that I found on YouTube to give viewers the basic premise of blocking. So enjoy watching the above video about blocking.
Until my next, happy knitting!
