Welcome, Melanie! I hope you are able to enjoy scrapping again without too much pain. I use a Wacom tablet and an ergonomic vertical mouse as my input devices and find them much more comfortable than a standard mouse. You have probably already considered similar alternatives, but I thought I would mention it just in case.
Hi (@Bookstamel) Melanie, always good to see a fellow Dutchie here (again). Welcome back and have fun scrapping! Would love to look at that book blog sometime if you have a link!
