Foolish cheapness
Are there items that you try to 'made do' with looooonnnng after it would have been sensible to have replaced/changed/serviced them?
And after you finally do, wonder 'what took me so long?'
My list:
rotary blades - dull or nicked
cutting mats - warped, cracked, or used so much that it is no longer smooth enough to cut properly on
rulers that have been used so much that the edge is curved instead of still straight
sewing machine needles
hand sewing needles - I keep on using one that has developed a curve in it
getting scissors sharpened
putting up with an iron that is not working properly
using an ironing board cover that is pathetic
