For my little cat's quilt, I decided not to use bias binding, but the system of self binding instead. Quilt back must be at least 2,5 cm/1 inch wider at each edge than quilt top to use this system. First of all, you have to trim quilt top and padding evenly.
On the wrong side of quilt back, mark a line 2,5cm/1 inch away from trimmed quilt top all around, then cut along line.
At each corner, fold quilt back so corner point of back touches corner point of quilt top and padding. Cut off corner as shown.
Fold trimmed corner onto quilt top diagonally.
Now fold raw edges of quilt back 6mm/o,25inch in to wrong side. Fold quilt back onto quilt top along one side, pin to secure. Fold adjacent corner onto quilt top, forming a diagonal mitre at the corner.
Now sew folded edge of binding to quilt top using a matching thread. Remove pins as you go along. Slipstitch mitred edges together at corners (2).
And this is the result: a happy cat. I took this photo a few minutes after I finished the quilt.
