I thought I’d share a bit about marking tools today. On this recent little piece, I used a washout blue pen as it was the only thing that would show up.
I buy a twelve pack of these on Amazon. They were recommended by Kelly Cline. The green marker here is used as an “eraser.” It is made by Dritz. You can fill it with water to make the marks disappear. That doesn’t mean it is gone from the fabric though. I only use the blue pens when I plan to thoroughly rinse and then wash the piece.
Instead of water, I use this in my pen. I bought this from Hab and Dash (bobbincentral.com). They no longer sell to individuals, but it may be available elsewhere.
All gone!
I love using this Hera marker! It was gifted to me by blog reader, Ila. 
You can use it to mark creased lines. It’s genius!
Here are three others I use, primarily on dark fabrics. I like the silver pencil, it wears away and washes out. It’s good on both light and dark fabrics. But it’s a paint to sharpen as the tip breaks frequently. This Fons and Porter ceramic chalk pencil is another favorite. It makes a nice thin line and it’s always sharp. Again, it washes or wears away. That fat chalk marker is easy to see and remove, but it doesn’t make fine lines.
I hope this is helpful. Your mileage may vary, but these work for me. No affiliations with any of these. Have a great day!

I need to get a hera marker! I appreciate seeing the different tools and getting your endorsement. I have tried some without knowing anything about them, only to regret the choice, as they never went away.
Thanks for sharing. I love my Hera marker!
That was helpful, Katy. I use the Hera Marker and masking tape a lot as well as freezer paper for motifs. Also love the Fons and Porter for dark fabrics. Thanks!
Thanks to Wendy for pointing you my way and thanks for your marking tips! It seems like your collection mirrors mine in many ways! I find the chalk in my red pen (bohn) not particularly grand but maybe I will revisit it again, at your prompting! Thanks so much for linking up (I’ll be doing it monthly on the 22nd – open till the end of the month! The more tips/tutes the better!!
Thanks for sharing this, Katy. Kathleen McMusing has a tips and tutorials linky on her blog – you should link this post up.
