This is a novice idea. Love the lime green towel too. I do like it very much.
You could ask the person (AuntVicsallwiredup) selling it. Unless it is second hand, they should know where the pattern is. Sorry, I can't give a link as it is on etsy.
I googled tea towel apron pattern and a lot of free info came up but I didn’t see this particular one. Are you making this for a child or yourself? It shouldn’t be too hard to figure out. It looks like two pleats at top edge with a band to fit sewed on. Pockets almost cover the bottom width. Ties at waist long enough to tie around. Neck strap may button on. I can’t tell on this phone. Sorry I didn’t find this one for you. Good luck
Thanks! I will ask my neighbor to let me make a pattern from hers. The square neck strap is a pullover. Hers is made for an adult, but I am sure it can be adapted for a child. I will wing it.
