As promised, I am sharing the chart for the leopard mittens I am knitting for my son. I haven't actually cast on yet, but I did spend the last day's worth of my knitting time trying to figure out how to let you all have a copy of it, should you care to have one. The solution is here:
It's a pretty standard mitten chart, designed for a dk weight yarn, knit on size 4s, for a finished size of 6.5 inches around. I am knitting mine with 2 skeins Reynold’’s Kids Playtime (which is not only soft, but also a superwash!) in beige, and 1 more in brown.
The size may be adjusted using the same graph by knitting in Fingering (knit to 8st/in)for smaller finished size (5.25 inches around), or Worsted (knit to 5 st/in) for the larger (8 inches around). Remember that the gauge is measured in pattern in the round.
I recommend casting on with 40 stitches, ribbing for a few inches before increasing to 42 stitches, knitting one row in the background colour to set up, and then beginning that chart. It will make reading the diagram easier to print out the chart first and tape the pieces together so that the lines match up. And don't forget to move the thumb to the other side for the second mitten.
I was thinking of several versions of the pattern you might consider, such as beginning instead with a cuff of your own design in the Latvian fashion, maybe adding some kente cloth colours and motifs for a little splash. (Like the 8 and 12 stitch repeat ones I put here) Or if you're feeling really ambitious, you could fill in the spots with a medium brown for a particularly leopard-y effect, either by stranding, or intarsia. Whatever apporach you choose to take, just have fun with it.
