You can donate old clothes and other things to the Diabetes Canada goodwill drop-off bins at their various locations! This helps raise funds for diabetes research. We are unsure of what they have in the USA and other countries, so if you are not from Canada and want to help, you may have to do some searching! It shouldn't be hard to find :) If you would prefer, you could also donate money directly to an organization that supports type 1 diabetes research (such as DRIFCan).
