The fluffy pink pig is finished and I'm rather proud despite how frustrating she has been at times.
The most difficult bit was altering the pattern - not a difficult thing to do with jumpers or socks as they have limited shaping, but requiring much more thought and planning with something that is mostly shaping.
The pig, as she stands (at 10" high, and 15" long), uses 5 balls of Sirdar Snowflake Chunky, which is approximately £12.50 or a little less depending upon where you buy the yarn. As for the stuffing, if you buy 250g Phoenix bags she takes two - that's another £8 or more. Again it depends upon where you buy the stuffing. If you are prepared to buy in bulk there are some great deals on Amazon, which brings the stuffing price right down. DK yarn I have not included as less than half a 100g ball was used and this can be sourced fairly cheaply.
Now to halve the measurements for a smaller, cheaper, more saleable piggy.
