you learn filling of a single diamond.
Two important points to remember,
1 filling always starts from left on the outline running anticlockwise.
2 in filling the count is down,up,down(needle passes down ,up,down at intersection of threads).
one point to cross check is.............
outline never touches fabric except at the beginning and end points. It is worked on the outline or skeleton .or else ... your outline work has gone somewhere.
STEP 1 & 2:
start from left as in pic..1
step 3: down i.sec 1, up i.sec. 2 and work in the outline to turn.
but wait... ..... just follow the step in picture 5 . work on the outline .
STEP 8 & 9:
pic 8 u see 4 intersections... count D,U,D,U.
Step 10: end at the starting point...remember...it did not touch the fabric :-)
