DIY sponge daubers for stamping / papercrafting

I have been having lots of fun crafting and trying DIY projects and wanted to share a favorite...
Sponge daubers from cosmetic sponges and PVC tubing!
Half inch PVC with the thicker wall's is best. The wedge sponges work well but I prefer the round. See attached photos...

Note... I posted this on my Facebook page last fall and forgot to post here. Enjoy!
