Template LQ QAL2 has additional circles to cover diameters from 6" to 8".
Inner Circle if you cannot print templates
If you cannot print this template to size, you will need to make an inner circle template using a compass. The diameter of your inner circle template needs to be one inch larger than the diameter of your dresden circle. For the following inner circle diameters, set the compass to the following distance between point and pencil and draw a circle on a piece of paper.
Diameter: 6" set compass to 3.5"
Diameter: 6.5" set compass to 3.75"
Diameter: 7" set compass to 4"
Diameter: 7.5" set compass to 4.25"
Diameter 8" set compass to 4.5"
Outer Circle - the best solution
Templates LQ QAL3 and LQ QAL4 cover diameters from 24" to 26"
Outer Circle - alternative solution
If you have already cut your fabrics and your circle is smaller than 25", Template LQ QAL3 (extension template) allows you to alter the ends of the outer circle template to compensate for a different sized circle. This will not result in a 100% perfect circle so I would only suggest using this solution if you cannot use the best solution above.
Outer Circle if you cannot print templates
Cut out a square of paper (I use newspaper because it is big enough) 14" square. In one corner, mark two lines 1/4" away from the edge of the paper. This point is the centre of the (quarter) circle you are going to draw.
Now take your ruler, put the zero mark on the centre point of the circle and make a mark at the 12" mark (for a dresden circle of 25"). The radius of the quarter circle template is half of the diameter and the diameter must be one inch smaller than the outer diameter of your dresden circle. For outer diameters listed below, you mark points on the ruler as listed below.
24" outer dresden circle diameter - 11.5" on ruler
24.5" outer dresden circle diameter - 11.75" on ruler
25" outer dresden circle diameter - 12"
25.5" outer dresden circle diameter - 12.25" on ruler
26" outer dresden circle diameter - 12.5" on ruler
Keep rotating the ruler and inch or so until you have a series of marks making a curved line.
Join these together to make your cutting line.
Cut along the cutting line to make your outer circle template.
Please feel free to ask for clarification of any of this in the Flickr group as I don't know how well I've explained it.
