Firstly, sorry for the late reply but very many thanks @Dave and @belugabob ... Dave, I will at some point attach or sew a little inner tube to the velcro straps (the posh 3m ones I'll have you know) so thabks for that... Belugabob, I did indeed make it inside out but upon educated guesstimates, I gathered that doing the back section inside out would render me with an inside out bag as it was starting to become rather stiff to turn it the right way round...
Added one last strap to the back (its a swanky D-flex one from my Rap*a top tube bag) to make it taut and reduce risk of getting soiled from the chain. Still looks a bit crude up front and up back but am happy with it and so is the little'un...
Thanks again all...
Oh... turns out my (misusses) cheap chinese machine ain't that bad afterall and remedied the thread breakages by swapping in the Gutterman as endorsed by Stu preciously on another thread. Now the problem is I've been through 7 sewing machine needles in total. 6 of Biessel wuality which are obviously not upto the job as they were grades 16 and 14. So, can anyone
suggest me some decent sewing machine needles that wont keep breaking every few seams
