knee patches were only a short term fix.
Not surprising, really. She only seems to be standing still if I ask her very nicely (and if she can wear her Princess T-hirt). Otherwise she's on the move - running, rollerblading, cycling. So some collateral damage is to be expected.
I made these drafting a pattern from some leggings she's got. But you could follow this tutorial. It's for making baby tights, but with some minor tweaks it's the same for these leggings.
Now, how quickly can I make another 5 of these?
