I have seen this meme floating around the internet for a while now. It made me stop and think about the definition of a crafter: a person whose occupation requires skill with the hands. If this is true, then buying craft supplies is indeed, a separate hobby from using those supplies to create art.
If you are uncluttering, you may want to take a look at your hobby supplies and equipment. Owning craft supplies does not make you a crafter; using the supplies does. Likewise, owning musical instruments does not make you a musician. You must regularly play the instruments to be considered a musician. You don’t need to be a virtuoso, you just need to enjoy playing regularly.
There are reasons why you may wish to keep certain things but make sure they are legitimate. When we moved to England, we kept our ice skates. There were no rinks in our area but we knew we would skate once we returned to Canada. However, my husband decided he would do recreational skating only so he donated all of his hockey equipment.
A friend of mine found that playing her clarinet while she was pregnant made her nauseous. She vowed that after the birth of her child she would pick up the instrument again. She started playing again when her youngest turned two years old and after a year or so, joined a small orchestra that accompanies a local theatre group.
Consider giving yourself a deadline for uncluttering unused equipment and supplies. For example, if you have not played your musical instrument or used your ham radio in over one year, you might wish to sell it. Put a moratorium on purchasing new hobby supplies and whatever you have not used in six months could be donated to a community centre.
Hobbies and pastimes are great but make sure you’re practicing the right one — using your equipment and supplies, not just buying and storing them.
