When I made my first pair of mittens a few years ago I came across the problem of how to block them. Nowhere I looked seemed to have any information on the best way to block mittens: should they be pinned out flat or simply shaped when wet, or something else?
I decided that the best ting to do would be to block them much like you would a pair of socks, over some mitten shaped form. But I had never seen such a thing for sale and thought it best to just make my own from my own hand measurements.
Much like my sock blockers tutorial, the first step to a custom fit pair of handmade mitten blockers is to get the correct measurements for your hand or the hand of your recipient. You want to measure around the widest part of the hand, above the base joint of the thumb.
Repeat this same process with the measurement of the thumb, making the rounded end rectangles that you cut for the thumbs between 8-10cm long. These thumb pieces should be cut completely independently from the main form pieces and not joined to them in any way. You should now have four pieces of cardboard or plastic matting. If using cardboard you should now cover your mitten blockers in sticky backed plastic or a layer of sticky tape to help waterproof them.
The thumb pieces are kept separate from the main hand of the mitten to make sure that the mittens will actually fit on the blockers, as with an attached angled thumb it would be impossible to fit the wet mittens onto the plastic forms. The great thing about making mitten blockers this way is that they can be used both for traditional mittens and fingerless ‘mitts’ and also work perfectly for mittens with thumb gores/gussets as well as afterthought or ‘peasant’ thumbs, as the thumb piece can be placed independently.
The making of the mitten blockers differs from the sock blockers in that there is no allowance made for negative ease. This is because generally mittens should not fit the hand ‘tightly’ not be restrictive in any way, just fit the hand ‘like a glove’, to the perfect measurements.
