Using 7mm knitting needle in the round which gauge wool should I use says Icelandnic alfisoi or loppi but can’t get this on England
You can use any yarn that gives you the correct tension / gauge.
Wool Warehouse sells Lett Lopi yarn, which is Aran weight. Lopi Lettlopi - All Colours - Wool Warehouse - Buy Yarn, Wool, Needles & Other Knitting Supplies Online!
Regular Lopi is somewhat heavier, so you might want a Bulky / Yarn group D? I don’t know what that weight is called in the UK. Rito sells Lopi in the UK: Ístex Álafoss Lopi - Icelandic Yarn at low prices - Rito.com
I can’t find anything for the other one you mention…can you check the spelling?
Thank you
