These super fine flower head pins by Clover are a must for precision piecing. Use them with Nova's Sew Straight Guide and a stiletto for great results.
"I recently acquired a 1953 Singer 301A and purchased your seam guide for it and also the oil/lube instruction card. Both have been very helpful. I watched your YouTube video on pinning from the left side and using fine grade pins. Who would have thought that the fine pins would make such a difference. They do improve seam accuracy."
