I was just reading that someone took a pattern from Karen Comb's book Celtic Illusions and enlarged it. The pattern is for a 24" wall hanging, and she enlarged it to 72". Not by making more blocks, just enlarged the whole thing. How would that be done? Thanks

Enlarging from 24" to 72" is simply three times bigger. For every piece in the pattern, subtract the ½" seam allowance from both the length and the width, multiply both by three, then add the seam allowance back to each.
For example, say there is a cut piece in the pattern that is 2½" x 4½". You would subtract the seam allowances (getting 2" x 4" ), multiply by three (getting 6" x 12" ), and add back the seam allowances (getting 6½" x 12½" ). So the new measurement for cutting that piece would be 6½" x 12½". Do that for all the pieces in the pattern. Probably the best way to keep track of it would be to make a list of all the pattern measurements in one column and then all the enlarged measurements beside them in a second column. |

since i'm lazy, i would tape the original to a window, tape a paper over it and trace. keep the original, but cut the copy into 9 pieces. remove the seam allowance. take the pieces to a copy store and enlarge each piece 3x. add the allowances back and tape the paper pattern together.
