What wonderful and creative ideas. Pumpkin pants! ha! Who didn't want pants like that as a kid (I know I did)?
Children. I admit it, I don't know much about kids. But they look like small sized humans with exceptional manual dexterity that only seems to get better as they increase in size.
I borrow my friends' kids as often as I can for work around the farm. My friends all live in the city so they like the idea of kids having somewhere to run around and expel
energy. What little do they know that when I say "child labour" I mean that the kid will be doing actual farming. I worry their expectations of what farmers do is a lot of lazing about admiring clouds. I don't really know what kids expect, I just do the everyday tasks that I would do with adults, only adjust the time and amount to match the individual's attention span and skill (so basically like working with adults).
Growing clothing plants is a lot like growing vegetables. I try to start them at this from about one year old or when they can walk unsupported.
Cotton is a lot of fun. Plant seed, watch the plant grow. They love harvesting the bolls and drawing pictures of the flowers (journaling is an important aspect of farming so I get them to draw stuff for me). Separating out the seeds from the fluff is an end in itself. At this stage, they just want the seeds so they can grow more plants. Then they find out later they can make yarn from the fluffy stuff!
Linen is a bit more tricky with kids because of the spikes. But they like growing it.
Working with wool can be done from an early age. Lots of different ways like felting, weaving, spinning.
The kids I've borrowed can start spinning at about three years old (I treadle the wheel and they do the drafting on my lap, then they get board and they treadle the wheel while I draft the yarn) and use a drop spindle from about four years old. I usually start them on a Rigid Heddle Loom at about 4 years old. But if they have an older sibling to guide them, I start them weaving younger. It's a great thing to have a loom set up for when we are cooking.
What I did in the past is to use the yarn they made earlier as part of the weft of their weaving. Then when the kids have gone home, I sew the cloth into a small bag for them to keep things in. That way they can see the finished product they 'made' from planting those cotton seeds and helping to feed the sheep.
Children seem to be remarkably good at understanding cause and effect over time. Much better than most adults I know (including myself). But at the start, each step is a goal in itself (planting the seeds, learning that we water the soil - not the plants, journaling/drawing, paintbrush pollinating cotton, harvest, fibre/seed extraction, spinning, weaving). Only at the end when they see the final project, they can look back and see the cause and effect which makes more excitement for the next time.
