No kilt (I've woven a great kilt though not from handspun yarn), but I've done a lace shawl (merino fleece) and a sweater (cotsworth fleece) and a pair of woven scarves (crossbred merino) starting from assisting with the shearing, washing the fleece, dyeing with natural dyes (on the shawl and the scarves), carding and spinning, and then finally weaving/knitting. And a linen tunic from growing the flax, retting and breaking/braking and combing, spinning (with a distaff no less), weaving and tailoring (all by hand).

Look for a local "Sheep to Shawl" demonstration to see all the steps. It's remarkable. It takes months to years for one person to do every step. It's remarkable what our ancestors did!
