hey every one , kieran here , im from ireland but currently living in canada , ive just taken up leather working as a hobby . so far ive just made a friction fit pocket knife sheath and about to make a pocket knife pouch , (i collect knives) any way i want to make a wallet but im having trouble finding templates with the different sections , if any body can point me in the right direction that would be great . i want to make a basic wallet with maybe a cash section and 4 card pouches , God bless and im looking forward to chatting and exchanging ideas in the future
