Cat, King of Mice is based on Jasper, my cat, who I adopted at age 11 and lived with me for an other 12 years. He was a hunter and loved chasing mice which he brought home as a present for us (not always appreciated!)
It is a pattern for interlocking filet crochet and overlay mosaic crochet

For the interlocking you might want to use the cotton, a approximately 5.500 meters
There are 3 files for interlocking: Abbreviation and instruction (including links to my YouTube file of how to do this technique), the pattern written and in chart and an extra large 8 page chart for reference of your work
it will be 115 by 157 windows and size will vary on tension but would be approximately 95 by 140 cm (38 by 58 inches) depending on tension

For overlay mosaic crochet you might want to use acrylic, of course you could use cotton here too, approximately 7.500 meters
There are 2 files for overlay mosaic, the written pattern (including links to my YouTube file of how to do this technique) and a large X chart for people who prefer to work with charts
It will be 219 by 315 stitches, roughly 112 by 160 cm (44 by 59 inches) depending on tension

The amount of yarn needed depends greatly on your tension, hook and yarn ply and I suggest you make a little trial of the technique you prefer (there are trail potholders with video tutorial of both techniques in my Facebook group)
