Thank you all for your kind words! The friends have picked the quilt today. They loved it and appreciated various details. They eventy asked how a quilt is made, sobota I showed them one that I had sandwiched but not quilted yet.
Solstice: I always draw patterns myself*, and I like to colour a drawn block with different combinations to try the effects. I use color pencils like those in schools, nothing fancy.
*I often use classic designs (I do not imagine that I invented the nine-patch, you know) but I always count the measurements of pieces to cut, number of blocks etc. from scratch. Most existing patterns have those in inches. Converting those to centimetres and scaling to my needs would be a nightmare, especially that even my usual seam allowance is 1cm, so simple multiplying and dividing would not work.
