The Folded Corners quilt block is an good choice for beginner quilters to learn technique. Two different patches are used in this block — the half square triangle and (my favourite patch) the flying geese unit, all set out as a nine patch block — probably the most common arrangement of patches.
This quilt block is a bit of an optical illusion — depending on the colour choices you make for the block. If you use fabrics in one colour family and place them as shown in the block image, you will get the desired effect — that being that the corners are folded into the centre. This, of course, is how the name of the block is derived.
(Side note: Yay! A quilt block name that actually makes sense!)
The “folded corners” effect of the block is actually lost in the two sample quilts I have illustrated — at least as I see the quilts. But, it was still a fun block to make and I enjoyed trying out all the different shades in several different colour families before I settled on this one.
