my yarn material cost $2.99 a yd I need 9 yd to make just one dog dress. I need enough to last me 2 months how much fleece would I need and how much would I be spending every 2 months on that fleece?

For my knitted hates, it cost me $3.99 per yd of yarn and I need around 10 yd for 10 hats. how much would I need to last me 2 months?

To make just one dog dress, you would need 9 yards of yarn, costing $2.99 per yard. So, for 2 months, which is roughly 8 weeks, you would need a total of 72 yards of yarn (9 yards per dress x 8 weeks).

The total cost for the fleece for 2 months would be:
72 yards x $2.99 = $215.28

For the knitted hats, you would need 10 yards of yarn for 10 hats, costing $3.99 per yard. So, for 2 months, you would need a total of 80 yards of yarn (10 yards per 10 hats x 8 weeks).

Therefore, the total cost for the yarn for the hats for 2 months would be:
80 yards x $3.99 = $319.20
