I had a lot of fun with the image below. Enjoyed not using traditional colours for the hair!  Another easy image for those just starting out with SN pens.

Hair: BP1, BP2, BP3, BP4, BP5 & BP7  Saturated using the lightest colour (BP1) Then straight in with the darkest, (BP7) working my way through back to the lightest pen.  As always when I'm doing the hair, I do find it easier to pick out where the lightest would be, then use the lightest pen or leave white for an even more lighter spot.  Just remember to not go over this area with your darker pens!

Face and hands:  FS4, TN2, TN3, CR3 & CR1.  Any time I am choosing my colours, I scribble a little of each pen onto pure white card as a key.  This is good practice because if like me, you will put the pens you have just used back in the tray holder then later realise you have missed a bit and for the life of you, you cannot remember the exact colours you used!  That only applies to scatter brains like me hehehe!
Again I lay down the lightest colour, then went in with darkest back up to lightest.  You might find it easier to blend if you use small circular motions.  You can add the cheeks at any point but be sure to blend them in with your base colour (lightest colour, in this case FS4. Well it isn't actually the lightest, I do find it quite difficult when crossing over from numbers to decide which is the lightest so I tend to use the one I like best!

Cup:  IB1, IB2 & IB3.  I'm in my comfort zone when using pens from the same letters.   I didn't really need to blend around the flowers on the cup but decided to do so to add more interest (rightly or wrongly). As long as you are happy with your finished result, that's all that matters. Starting with lightest colour covering whole of the cup then quickly working in from darkest to lightest for easier blending.  Remember! Blending is much easier if the ink you are layering your darkest colour onto is still wet.  So when colouring larger areas it is always best to do a little at a time.....Okay, so I've explained that to you....but will I ever learn!

Flowers: GB1, GB5, GB7 & GB8.  Again putting a layer of the lightest colour down then working back from darkest to lightest, blending each colour each time.
