Knitting these around styrofoam eggs from Panduro (isopor-egg). I think the ones I use are 6x8cm.

Had to modify the pattern a little to make it fit the eggs I use better - knit 4 more rounds before first decrease, and after I decrease to 4 stitches per section I knit 1 round (instead of 3), decrease to 2 stitches per section, knit one round and then finish - the butterfly pattern shows the modifications I made.

The eggs are a gift for my stepmother :)
