I can only point them to...

Does the highlighted part mean "as new studies show that learning some hand skills are very difficult for little kids, whenever I encounter someone who suffers from dyslexic or dyspraxic disorders I rapidly remember those hard classes of sewing and stitching"?

Context:

Years of my life were taken up trying to perfect sample stitching (hem stitch, stem stitch, French knots and Lazy Daisy), embroidering a hot-water bottle cover and knitting a pair of ever-expanding socks. I also became acquainted with the arcane skills of drawn-thread work, appliqué, crochet and tatting. My efforts were neither pretty nor useful and the cries of ‘Unpick! Unpick!’ still ring in my ears. Neatness and precision were all-important but I acquired skill enough and might yet show Tracey Emin a thing or two. If subsequent child development studies have shown that it is difficult for children to acquire fine motor skills until a certain age, diagnosing those who struggle thereafter as dyslexic or dyspraxic, I can only point them to samplers cross-stitched by average six- and seven-year-olds in the past. That some of the fabric was pin-pricked with blood was thought of as suitably corrective. We were under strict instruction and the only ‘creative’ say we had in the matter, provided we were good, was a chance to choose our colours from a limited selection of embroidery silks or wool scraps.
