Thrums first showed up on hats http://www.isca-morrismen.com/monmouth.htm:
"By the eighteenth century, the woollen cap worn by the ordinary sailors in the British Navy had changed to the Welsh Wig which was described as a round knitted cap which may have originally been the "Monmouth cap". It was often knitted of thruns, where the multiple broken ends were left outside the cap and may have helped to make the cap warmer and at the same time given it a hairy appearance, probably giving rise to the nick-name "Welsh wig". These caps seem to have been used in military and naval hospitals even up to the present century. The name that survived to be used again on a cap that was developed for the rigorous climate of the Crimea and which was only slightly different from the "Balaclava" cap, which was developed at that period."
(I do have plans to make a Monmouth cap in the future.)
Back to the Thrumbelinas! (They're on sale thru the end of February, in case you're interested in making your own.) The upfront work of making the thrums is a bit time consuming. I needed 122 for the regular and I think 142 for the large. That's for one slipper! I know that the method that Michele used is different from what Sheila is used to seeing, so no right or wrong way to make them I guess. I took the large one to an SCA event I was attending last weekend and they received LOTS of interest and thoughts that they would make excellent camp slippers. So I'm going to be dipping into my leftover Lamb's Pride yarns and some of the sample rovings I still have from the World Wide Spin in Public and making a few pairs for us and friends I think. There was also the discussion of adding leather to the bottom if they were camp slippers.
Here's what they look like on the inside:
These are knit flat with an i-cord along the sides then you join in the round to complete the toe with a quick mattress stitch seam up the back to complete the slipper. If you leave a long enough cast on tail, you'll have plenty to do your seaming!
Spring may be coming, but its still cold enough for slipper wear around here until at least mid June. If you make a pair, please let me know! I'd love to see the different color combinations people come up with.
