The Slip Knot quilt block is sort of an optical illusion, in that it appears that fabrics weave over and under.
At first glance, this might look like a difficult quilt block to construct, but it contains only simple squares, rectangles and the two most commonly used patches in quiltmaking — the half square triangle and the flying geese unit. To be successful in sewing this block, you need only to be able to sew a precise quarter inch seam allowance, due to the number of cut pieces and resultant seams in the block.
I even made the pattern easier for you to sew by taking a few liberties with the design. The original block features only squares, and no rectangles. It made no sense to me to sew two or three squares together to create a rectangle. And so, in my version, with fewer seams to sew, you will have greater success. (You’re welcome!)
The two sample quilts illustrated here are both sewn with blocks on point, but by choosing different options in the construction phase, I ended up with two very different quilts. Now it is your turn.
