Hi Everyone;
I thought I'd start this thread since we all have that one little item which didn't cost a lot but is a total game changer and we would always buy again / recommend.
I'll go first:
These little pins for putting in / aligning gussets. I bought them on ali express for only a few dollars and I love them way more than just using needles (depending on the design, the needles would slip out of the pre-punched wholes and also I hurt myself several times with them....)
What's your little item?

One of my best cheaper tool is a japanese diamond awl for sewing! I don't remember if it was from Seiwa, Oka Factory or Kyoshin Elle... I have mixed brand tools. But I love it!🥰 Is similar to the one in the link.
