I am not the biggest techie and only have a few apps. Its is a free fabric calculator, it’s not a design app but will let you quickly see various design, colour and layouts. That is something I thought was brilliant, as I often just make blocks up and wing it – I have run into problems with some log cabins in not ordering enough of one fabric and this will stop all that!
There is a library of commonly used quilters blocks and it allows one to place in the size of the block and also the number of block one would like to make – then it calculates all the fabric needed! So clever.
Do you have a favorite app?
