for the direct link to buying this book from my Amazon books store.
A pre-prepared pad of 'dots' where you can draw your line and even better show you where you pass the treble.
Sure you could use scraps of paper or even graph paper and lose track of what place you have got to or what was your last attempt or where can I find another sheet of paper...
With this pad, you can look back and check where you were going wrong and just practice that bit.
So when you next get to the tower you will be confident and motivated to show your progress.
You can even have the pad with you and between times draw the line again for the part that is still frustrating you.
This pad is for doubles & Minor and laid out Vertically.
