Your snowmen are beautiful!
I recommend Tsukineko ink. You don't have to buy a whole set. You can buy just 1 bottle of ink if you like - maybe the Cherry Pink or the Red Delicious. A little goes a long way. I have been using the same set for about 10 years.
I have tinted the complexions of people in several quilts with these inks. Works beautifully.
I would put a drop or two of the ink in a little water and apply it to some dampened white cotton cloth with a Fantistix coloring tool or a watercolor brush, to test first. It will blend better if you apply it to damp fabric. Then heat set with an iron. Start out light. You can always apply it again a second time if you want more color.
For my projects, if I decide I want a different color, or it is too dark, I just rinse the color out, let it dry and start over. This assumes I haven't heat set it yet.

I would use a small iron, like the little Clover iron, and just press the inked area - so you don't flatten your beautiful applique.

I love to try different mediums on fabrics. I paint fabric with fabric paints, Procion dyes, Shiva Paintsticks, the Necololor II watercolor crayons, fabric markers, etc. I think the Tsukineko inks would be the best way to go with your gorgeous snowmen.

Yep! Agree with BJ...you can do it ! Just start with a light hand...and persevere !

You won't ruin it. I do all my quilting on some of my borders and then paint them...scary, risky, but often provides the best results. Cheers.

Thanks for the suggestions. I appreciate all of the help I can get. I have realized it would have been better to do it before they were appliqued so I don't ruin it now.

Love your snowladies. The others have more experience than me, so I would experiment with the crayons.

Probably right Marilyn...small and light in color.

As I said....many choices these days....pigment dye is always most permanent...whatever the medium.
but this is pale pink after all....and small....Inktense pencils are popular just now....$25 however...
Crayons have done well for me. Bigger project...maybe a bigger tool..

They are darling, would love to see them with the dab of color!

Marilyn, I did have my regular crayons fade out substantially in a test I did. Perhaps I didn't do it right. Probably a test is in order, but I do think the fabric crayons are a wonderful addition to the studio. See Kathy McNeil's dvd they have in the guest DVD section where she demonstrates the use of these crayons.:

No need for "fabric" crayons....plain ol' Crayola works just fine! Check tutorials by Crabapple Hill Studio's Meg Hawkey.
Shiva sticks are $$.

Delightful! I think you could use either fabric crayons Ifound here) or Shiva sticks (found here) for that. Probably I would choose the fabric crayons. After heat setting they are both permanent. Check out my blog on paints here. I'd love to see pictures after you get it finished. Cheers.

Absolute sweeties, your snow ladies. I would also try a dab with the crayons

Really like your snowladies! I agree with Marilyn.

Little cuties...I wouldn't have appliqued them either...while there are many products...I would use crayon and heat set when done
I'm sure there are lots of instructions on-line...but easy thing for such a small area. Permanent. Do a sample.
