Hi, I was looking to get a short youth recurve bow, approximately 28 inch length. I tried out the Old Mountain Little Hawk https://archery.ixpesports.nl/contents/nl/p19662.html
, and it was perfect for my kids. The Lil John bow https://www.3riversarchery.com/lil-john-youth-recurve-set.html looks similar. However, I need a left-handed bow, which is not available.

Any bowyer's around here have experience making a short youth recurve? Any plans available?

I don't know of any plans.  I have made 36" recurves for kids.  I used 1.5" glass the riser was about 12".  The limbs were straight no deflex with small recurves.  They worked out pretty good.  I could get a bow from a single 72" strip of glass.  Haven't built one in several years now.
