Absolutely LOVE these stitch markers. Saw them being used on a YouTube video demo and made a mental note to check into them. The safety pin style plastic are nice, but I hate having to stop and fumble unlocking/locking them ~ Drives me batty at times! Just happened to be visiting Homesewn with a friend and looked down ... It was like the Heavens opened up because there were the Split Ring Stitch Markers in a cute little package!!! Delighted that they are weighted ... made of metal and enameled in six vibrant colors. Came home and switched out ALL of my markers with these ones!!! Truly cannot say enough about them ... no fumbling, can hold as I crochet and insert, super reliable and don't get in the way!
