My parents got a new slim tall Christmas tree this year. The old tree skirt was just too big (even after taking and trimming it with scissors). No stores really seem to sell small (like 36 inches or 30 inch diameter) skirts.
So the Christmas tree got a simple full circle skirt with lace and fleece backing.
First up was estimating how much fabric to buy. Guessing, 15 inch waist for the tree (because I didn’t have the ability to measure it) and back calculating to check to see if it is a reasonable pole diameter. Remember that the circumference of the circle is Pi multiplied by diameter. Estimated pole was 4.5 inches. Outer radius for bottom of skirt was estimated at 20.25 inches (for around 36 inch skirt diameter). So I could squeak by with 1.25 yards of fabric (that is with 5 inches of extra space. I told my mom 1.5 yards just to be on the safe side.
After we picked up the fabric, I measured the tree. Its waist line is more like 7 or 8 inches instead of 15. Also, my parents decided on 30 inches diameter instead of 36 inches. All the math had to be recalculated. Since I didn’t pull back up the circle skirt calculators from the internet, I had to make sure I added at least 1 seam allowance for the waist. It is a case were smaller diameter will be fine.
Half circles were cut. Lace was applied to the outer layer. Then fleece and outer layer were stitched together with an opening for turning it right side out. Everything then was top-stitched closed.
