Lovely commentary/pics thanks

On the Vaal we only really get the two caseless (netspinning) caddis species but from my Oz/Pom days cased caddis especially the dudes that make their cases from bits of twig and stuff as opposed to sand, would be beautifully imitated by your creation.

For the 'peeking' head I often used a bit of 30lb Cortland fluo yellow braid, the same stuff I use striped black and greased in 15/50cm lengths for a CZN 'indicator'. I also singed the end with a cigarette lighter. Another excuse to enjoy the odd cigar!
