A machine needle can sew through the flower heads with ease. I have had to remove a few stitches from them before!

I use them. They seem to work for me for piecing and pinning things together. I had to buy another pack of them for my current quilt (and those bent quilter's saftey pins) because I ran out trying to pin the borders down flat.

I use mine to pin my quilt tops and backings onto my LA rollers. They work great!

I love mine.. they are super thin and I do use them for piecing but pretty much useful for anything.. Then I bought what i thought were the same ones- since I used them for everything and wanted more on hand- but they were 'thicker' and I didn't like these new one ones at all.. made to big of holes in my fabric..

This is how I use those yellow quilters pins. Rather than having the pin hang out of the edge, I put them alongside where the stitching line will go. Then I don't have to worry about running over them with the sewing machine and because they're long pins, they cover a good size area.

I use them on my design wall to pin up notes, directions, or large heavier fabric if needed.

I use them all the time. They work well for me.

I only use the yellow head pins for one thing, when I am down on the carpet layering the three parts prior to basting. They are great to hold all layers taught whilst I baste. I do not use them when actually sewing the quilt, I prefere to use ordinary dress makers pins foreverything else.

There is more than one size of the yellow head pins. I don't use the heavier ones, but I use the thin ones all the time. I also use very fine silk pins that I can even sew over when I don't want any shifting when sewing over seams.

I used to use them all the time , till I started sewing on Batiks. they are too thick , and leave holes in the finely woven batik fabric. After having discovered really super fine pins it felt like I was driving nails into my fabrics.
I have them on a seperate magnet , and use them on my desing wall and pin in what will be the seam allowance.
